Hello All,

I have developed an outlook add-in in visual studio 2008 with framework 3.5. This add in is working in almost all windows OS and it is not getting loaded in a particular scenario. One of my client's PC is running in 32 Bit Windows 8 and he is having 64 bit processor. When he installed my outlook add-in after configuring Office 2007(I successfully tested this with Office 2010 in same PC.), I was unable to find the add-ins listed there. After digging into I have found that the add-in is not loaded and I got the following exception.

mscoree.dll : Not loaded. A runtime error occurred during the loading of the COM Add-in.

After reading some blogs regarding this issue, I have added a fusion logging to see what is happening.
