Hi Viv .. thanks for replying.

This is an exe that had been working (another Colleague was doing the development , has left and I copied over app to my PC)
It had been working fine on Windows Server

By 'load it up' I mean just copied up the .exe to the server. (which also happens to be 64 bit ...dont know if this makes a difference)
Nothing else should have changed



When the Exe is run on the server, it immediately opend a Windows Dialpogue box which says: MyExe has stopped workiong and there is a dropdown to 'View problem Details. if I view problem detail, it comes up with about 9 'Problem Signature s'
Most just identify the .exe, version numnbers. One of the Problem Signatures says: System.IO.FileLoadException



Regards,
Gerard
