I have created a Installer for my Outlook add-in. It works fine on windows 8 and windows 7 with both 64 bit OS and 32 bit OS and office 2010 and 2013. My problem is with windows 7(64-bit) and MS Office 2007.
Registry entry is created fine in the location :
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\Outlook\Addins\myAddin
Also load behavior is 3 Load behavior is 3 when outlook is opened first time. But I noticed one more thing that if i go into inactive add-ins and try to activate my add-in then the load behavior changes to zero.
I have also checked "VSTO_SUPPRESSDISPLAYALERTS" for any vsto error messages or exception but no exceptions are there. Please help me out. Thanks in advance
