Step 1, Launch Microsoft Outlook 2010, either by locating it within the list of programs under the start button or by double-clicking its desktop icon.Step 2, Click the File tab in the top left corner of your Microsoft Outlook window ribbon. The ribbon is the new term for Microsoft Office applications' main toolbars. While the number of options may seem more limited than those in previous versions, it is simply that Microsoft redesigned the menus to make them more intuitive, concise.

“I installed my Office solution (VSTO add-in) successfully but when I open the Office application, my add-in does not load. What is the problem?”This is a common question which I came across many times in Forums. Here are simple and quick checks that you can do before you start scratching your head or jump to the Forums. I’ll be using Excel as the Office application, but the approach is applicable to others more or less.1. Make sure your add-in is installed correctly and it is enabledOpen registry editor and navigate to “ ”. Here is how this registry key looks like after I installed MyExcelAddin:The registry string we are interested in the most is the LoadBehavior.
Whenever you see '3' (Loaded at Startup) as the value of this string you are good in this part and your add-in tries to load when the Excel starts. For more information about registry entries for application-level Office solutions see.2. Check out “COM Add-Ins” dialog in ExcelNow open Excel and see if your add-in loads successfully.
If not, open Excel Options dialog (File-Options) and navigate to Add-Ins tab.“Healthy add-ins” show up as “Active Application Add-ins”, however, if an add-in is disabled for whatever reason, it will appear under the “Inactive Application Add-ins”. You can select the “COM Add-ins” from the Manage dropdown at the bottom of this dialog and see the LoadBehavior of all COM add-ins. In normal cases, the add-in should be checked and its 'Load Behavior' should be “Loaded at Startup”:If the VSTO runtime encounters a problem loading the add-in, you’ll see this message instead.“Load Behavior: Not Loaded. A runtime error occurred during the loading of the COM Add-in”.3.
Find the problemSet the 'VSTOSUPPRESSDISPLAYALERTS' environment variable to 0. Then go back to the registry key I mentioned in step 1 and set the LoadBehavior to 3. Now restart the Excel. You should be able to see a dialog describing what is happening:It is also a good practice to enclose the code inside the add-in's startup event in a try-catch block and log all exceptions.4. Hard disabled add-insIf an add-in causes the Office application to crash (close unexpectedly), the add-in gets “hard disabled”.
Please follow instruction to re-enable the add-in. In addition, you might want to check the “HKEYCURRENTUSERSoftwareMicrosoftOffice 12.0ExcelResiliencyDisabledItems” (replace 12.0 with 11.0 for Office 2003 and with 14.0 for Office 2010). Your add-in should not have an entry under this registry key.More References:. Hamed, I've done all steps as mentioned in your post, but I couldn't get my addin for Outlook 2010 enabled ? I've set VSTOSUPPRESSDISPLAYALERTS = 0 too, but No Error dialog popup. But add-in does not get enabled.
Load Behaviour is set to 3, but as soon as outlook 2010 loads, it gets converted to 2.Can you help me here?. It is really getting irritating for me, since I could not produce an exception box so that i can know where error is occurring My Dev platform works fine. It happens only on client PC. The PC has Office 2010 32-bit, Windows 7 x64,.Net 4.0 Client Profile and VSTO 2010 runtime already installed. Hi Varun,Let me clear some points first:1. I am assuming your VSTO solution targets.NET 4.0 client.2. Are you using MSI or ClickOnce?

If MSI, have you verified that all required registry keys are created? What Office 2010 and VS2010 you are using? Can you give me the build numbers?4. Have you wrapped the entire code in the addin startup within a try-catch block? Any exception?5. When you say 'it works fine on the Dev platform', are you debugging on the dev machine or you really installed the addin?
![Mailstore Mailstore](/uploads/1/2/4/2/124242162/212954213.png)
(please note that you need to do a 'clean solution' on the VSTO project in VS before installing the addin on your dev machine and uninstall the addin if you want to go back to debugging!). Also what are differences between your dev machine and target one? Different OS, VS, Office? (even build numbers or the order you installed these).6. Do you have ANY other addin on the PC target that works?7. Do you have any other machine (preferably similar to the dev machine) that you can install the addin?Hamed.
Yes, solution targets.Net 4.0 Client Profile2. Using MSI Installer for deploy. And all mentioned Registry entries exists.3. Version Info:VS 2010 Ultimate – 10.0.30319.1 RTMRelOutlook 2010 – 32-bit – 14.0.4760.10004. Yes, I've wrapped the code in try/catch but not working. Also, you should know that the project was originally in VS 2005 for outlook 2007, and have been upgraded to VS 2010 recently.5. On Dev machine it works fine in debugging way, I've not tried installing it on Dev machine.6.
No I don't have any other addins on the PC7. Yes, the OS and Office application are same on my Dev machine and a test machine. WIndows 7 – x64 and Office 2010 – x86.I'll update the result of the troubleshooter tomorrow.and Thanks for looking into this. Ok, a few suggestions to help us here:1. Since you migrated the solution, first take a look at this blog post, might be helpful:2.
Can you create a new 'Hello World' Outlook addin with VS2010 and install it on the target machine and see if it works fine (use the same MSI installer approach). Please put no code but a message box or something indicating that the addin has been loaded. Would be a good idea to have an excel or word addin tested too.
I am trying to find out if the VSTO runtime is doing what it is supposed to do. Here is some information on the manifest:Since you are not able to load/run any addin, I would say the machine is not in a good state. Because the VSTOSUPPRESSDISPLAYALERTS does not show any issue, it looks like we do not even get to the VSTOLoader and everything fails before that (for instance loading CLR).1. Since this is Win 7, you should have.NET 3.5 installed. I would suggest creating a 3.5 solution and test that as well, just to make sure it is not the.NET version specific issue.2. From the screenshot, I see that you have both Office 2010 and 2007 installed. Any reason for that?
In what order you installed them? Look here for more information on having Office versions side by side:3. If it is easy for you to reimage the machine, I would suggest that. Just install things in this order:.NET 4.0, Office 2010. Troubleshotting a machine in a bad state might take longer than reimaging the machine. Hamed,Though I got the addin to work on 32-bit, I would still like to answer your questions 1. I got the toolbar loading properly in Outlook 32-bit, it was a Manifest key value error, I had used.manifest in that for office 2007 solution but I had to us.vsto vstolocal for this to work in 2010.2.
No, i do not have 2 versions of Office installed. It is fresh installed test machine. Only had WIndows 7 – x64 and Office 2010 – x86 on it.Also, if possible can you guide me why would this addin of mine gets installed properly for 64-bit version of office and the Addin has all the same Registry values in Wow6432 node under HKLM/Software key. But Outlook does not detect it. It does not show in Add-Ins Tab of Outlook Options.
Do I've to create a new project to target 64-bit version of office? In my existing project I have platform = 'Any CPU', I thought it should work if registry entries are under 64-bit Registry nodes. Isn't it?Thanks. Glad that your addin finally loaded.Sorry about the Office 2007 comment, I misread the screenshot. The value in front of Office 2007 is 0, i.e.
You did not have Office 2007.the 'vstolocal' is required for msi deployment because it tells Office to load the manifest from a local installation folder not the ClickOnce cache. This is described in this document which has been pointed out before in our discussion. I believe the 'vstolocal' is required for both Office 2007 and 2010 solutions because ClickOnce is available for both of these Office versions. Also here is another forum thread talking about it:.The bitness of Office does not matter. Registry keys always go the registry hive that matches the OS bitness. Your registry keys shold go under Software/Microsoft/Office/AppName, not under the 32 bit hive on a 64 bit machine (i.e. That is why your addin does not show up.If you target 'Any CPU' you should be able to install the msi on both 32 bit and 64 bit machines.
Trying to post this again; didn't seem to work. Apologies if this is just some delayed posting mechanism with no notification of that process.I'm currently trying to get a new clean Excel Add-In to open in Excel and am hitting this same LoadBehavior changing from 3 to 2 problem.
The difference here is that if I set the value for LoadBehavior to 3, and run Excel outside Visual Studio, my Addin loads fine and runs fine. The add-in code itself is quite mature and robust; I've just migrated it from VSTO2005 to VSTO2005SE because Microsoft pulled the availablility (or so it seems) to VSTO2005 and either way this problem happens with a clean new Excel Add-In so this it not a problem with any code I have written. The part where LoadBehavior keeps changing to 2 is when I try to run the solution from Visual Studio. When I do that, Excel starts and nothing else happens. When I check Add-Ins my Add-In is listed as enabled, it is not prohibited; it just doesn'tload or run (no break points anywhere are hit.) VSTOSUPPRESSDISPLAYALERTS = 0 does nothing useful (actually it does nothing). The only thing that does happen is that registry key value changes from 3 to 2. If I manually edit it to 3 again I can run Excel outside Visual Studio again and my add-in works fine.
This is purely a Visual Studio problem and what's more with the default Visual Studio project settings for an Excell Add-In. Seeing the purpose of upgrading this Add-In to VSTO 2005 SE was to be a code sample for our users the fact it won't run from the development environment is a deal breaker. This is actually the intended use case in this instance; to allow users to learn about developing against our object model.I've got a lot of experience with VSTO 2003 and VSTO2005, but not much with VSTO2005SE, but it appears that the trend of being extremely hard to use and configure (and debug) continues with VSTO. I do like the Add-In approach, but a new clean Add-In failing to run feels like a class A fail, IMHO. ?By the way I'm running VS2005, and Excel 2003 Professional on my dev machine; companies with massive code bases cannot be as nimble as others who upgrade to the latest version the second it is released, so hopefully someone might know a little bit about why this may be happening?Thanks in advance. I did some more testing on my issue and found that when I start Excel as per normal (my OS is Win7 32-bit, virtual machine) my Add-In loads and runs just fine.
If, however, I start Excel as an Administrator it does not load and changes the LoadBehavior registry key to 2. Now why did I try running as an administrator? Well, since I am running VS2005 on Win7, it has 'issues' running on that OS and the recommendation by Microsoft, I believe, is to run VS2005 as an administrator. It's annoying to do, but until my company upgrades to VS2008 (which I use a bit at home) or VS2010 I'm stuck running VS as administrator. I tested this by NOT running VS as an admin and it works, I can hit break points and everything. I take back what I said about ease of use for VSTO2005SE; it's just my luck to hit this stuff I guess.OK, so I've found the root cause of my problem, but my question is why running as an admin would prevent the Add-In from loading? Surely running as an Admin should be better than running as a regular user should it not?
Or is this some secuirity enforcement to not running add-ins with admin rights? If that is the case I can accept it and perhaps even understand it, but if possible I'd like to confirm it so I can pass that information on to my users. Hi Hamed.I read all the previous information carefully, but no one trouble relates to me. The problem in that i cannot load the WBS Modeler add-in for Visio 2007.
It isn't shown in Visio 2007 menu after installation.I checked the registry key and found out that everything is ok with installation, even Loadbehavior value is set to 3. But not in list of COM Add-ins in Visio 2007 nor in menu, WBS modeler is shown.Help me this way please, cuz its connected with my job and i cannot do the things right without this add-in. Hello, I have a problem connected with Office 2007 and VSTO add-in.Description:Windows XP SP3 x86MS Office 2007 x86 (Enterprise edition)My VSTO add-in is not shown in the menu.HKEYCURRENTUSERSoftwareMicrosoftOfficeExcelAddinsMyAddinLoadBehavior = 3In Add-Ins tab (File-Options) I can see that my add-in is active. There are no any exceptions.I can reproduce this issue in the following order:1)install MS Office;2)install add-in–.net framework 2.0 is installed;– add-in is installed.But if.net framework had already been installed before I installed the Office — add-in works in the right way.1)install.net framework 2.0;2)install MS Office3)install add-in—- add-in works properlyOn Windows 7 x86 (Office 2010 x86) add-in works. Maybe because Windows 7 already contains.net framework.I can't resolve this issue Maybe you will be ableThank you in advance!. Even i have similar issue with my VSTO Add-in. The add-in loads only for new file but not for existing files.
What may be the reason for this kind of behavior?After restarting the machine, issue gets resolved. But after some time, again add-in wont load for existing files.Settings:1. Technology: Visual studio 2010, C#4.0, MS Excel 20102. Registry: HKEYCURRENTUSERSoftwareMicrosoftOffice ExcelAddinsadd-in ID3. Load at startupTroubleshooting:1.
Have enabled VSTOSUPPRESSDISPLAYALERTS, but dint work.2. Options-Manage COM Add-in - Add-in is checked.(load at start up)Kindly help me out. I follow all the instruction but no luck, but my situation is bit different.I developed Outlook 2010 AddIns using VS 2013 Ultimate and It always can run on dev machine in debug mode as well when doing MSI installation. But now problem is when I install at client side even it didn't show in disabled Add Ins list, there is no error during installation.
Client Environment is totally different, they are using Win 7 64 bit on virtual machine. Important thing is even it didn't throw any error during installation but I cannot find installed add ins in registry under Office/Outlook/AddIns, try to search to find any entry to check load behavior but no luck so I kind of lost.
Any suggestionlooking very much for a help.
