Excel vsto Addin(x86 & x64 both) setup loaded successfully in Excel 2010, but failed to load in excel 2007

I have created the .vsto ExcelAddin.exe for both configurations(32-bit and 64-bit),using installshield wizard 2015LE in win7(64-bit), both are loaded and working fine in excel 2010, but none of them are loading in excel 2007,and displays the load status as below from excel COM add-in panel.

And Registry entry for the same is as below, enter image description here

Solution

  • got it..the registry key for 32-bit office excel 2007 in 64 bit windows system is different,therefore I replaced the key from [HKEY_LOCAL_MACHINE\Software\Microsoft\Office\application name\Addins\add-in ID] to [HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Office\ap‌​plication name\Addins\add-in ID] during building the setup exe.
