I made an webapplication which runs fine on a windows 7 (64 bits) /IIS7 combination. App pool is asp.net 4, integrated, 32 bits apps allowed.
I want to deploy this app to windows 2008 r2 (64bits) /IIS7. Same app pool settings. So i copied the files from the WIndows 7 machine to the windows2008 r2 machine.
Now i'm facing with an error message like xxx.dll cannot be loaded, bad image format.
What could be the problem?
