I have a small program that works just fine on Windows XP boxes. However, when I run it on a Windows 7 box, I get a SSPI error. As you can see, all it does is copy a file and exit it. I am wondering if the "shell" is the issue.

Code:
Private Sub Form_Load()
Dim filefrom As String
Dim FileTo As String
Dim Command As String

filefrom = "Z:\PARTS\MACHINEPARTS.EXE"
FileTo = "C:\PARTS\MACHINEPARTS.EXE"
Command = "C:\PARTS\MACHINEPARTS.EXE"

'first copy file

FileCopy filefrom, FileTo

'now fire up the program

Shell Command, 1

End

End Sub
