Hi,

OS Windows 7 x86 AND x64
Excel 2007
Fresh install

I am trying to open an excel file that is a part of a small software. The whole thing was developed in a Windows 7 x64 developer environment and works fine under XP and Vista. It needs to have .NET 3.5, Interlop Assemblies and Visual Studio Tools installed. Under Xp and Vista I would normally install them and have the software run just fine.

However, under windows 7 x86 and x64 this is not the case. I managed to insall Interlop Assemblies and Visual Studio Tools (I understand .NEt 3.5 comes built in Windows 7) but when i try to start my software in Excel, I get a crash window with the following error:

By the way, there is a VSTO involved but it seems to install succesfually...or so I think..but I may be wrong! VSTO installs the first time you run the app and if unsuccesfull then it will try to install each time I start the app. I think it was installed succesfully becouse it does not show up after the first launch.



You will be my HERO if you help me solve it !!!
