I have a Foxpro 2.6 for Windows application that is not running.

When I run the EXE from Explorer on my hard drive, I get the message:
Product is in use by another

When the user runs the EXE from her hard drive, she gets the message:
I/O operation failure

When I run the EXE from my computer within Foxpro, it works fine!

Does anyone have any ideas about the cause of this problem.

Thanks
