Help!

Has anyone experienced the following problem with the setup wizard and installation in VFP 5.0a?:
I have been using this wizard for several years without a problem at a client site for installations. All of a sudden I get the error message,'Setup could not open the file. C:\ACT\Acct.dbf', when installing the app. I tried re-compiling it several times with the same results. Also I tried another app and the setup did the same thing. I had older versions already compiled and they worked fine. I then re-installed VFP 5.0 and the service pack 5.0a with the same result. I am completely puzzled! Does anyone have a clue to why this is happening and what I can do to fix it? BTW, I made sure the virus prg was disabled. Thanks much.

Regards,

Bill T.
