I made a Word add in application in VS 2010 in C# and it was working fine until I installed the app using Advanced Installer in my development PC and its doesn't display anymore in the Word ribbon. I check the registry files and it looks fine, tried to add the same registry keys in the HKEY_CURRENT_USER and the HKEY_LOCAL_MACHINE directories in the registry Editor window but still no effect.
I even create another add in as a test and it wasn't displayed in the word ribbon.
When I check the Addin options in the Word option window the addin is located in the Active Application Addin which indicates that addin is loaded and working but still can't be displayed in the word ribbon.
I also tried to re-install the whole office package and restore the PC configuration to the date before installing the app but still nothing works.
The registry keys I use for the Addin are listed below:
Description: My_Addin
FriendlyName: My_Addin
LoadBehavior: 3 (DWORD (32-bit) value)
Manifest: file:///C:/Application folder/My_Addin.vsto|vstolocal
