Hi Patricia (and everyone else who might have an idea here!)
No joy. I logged into her PC this morning and her UAC is set to off. She shuts down every night, so she has been rebooted. Still got the same message. ???

I am going to try while she's logged into the network as Administrator. Though, as I said earlier, I am able to create, modify, and then delete a text file in the APWIN folder.

FRUSTRATING!

Thanks,
Carol
