I\'m using Classic ASP.
Set theForm = Server.CreateObject(\"Persits.Upload\") theForm.OverwriteFiles = True
Running the above code produces
Comprehensive Check-list I posted here
Error ASP 0177: 8007007e Server.CreateObject fails for COM DLL
Deals with the issues of registering DLLs for use in Classic ASP for both 32 and 64 bit and common problems encountered.
Would post it here but don't want to duplicate the answer.
