Error reading file c:\users\dmitry\appdata\local\temp\password.fxp

Dmitry, on further reflection: IME VFP usually unpacks the exe into memory so it can run. Therefore if the fxp is in the exe, I am not convinced that your app is trying to read just this fxp from the exe on disk.

Perhaps there is more than one copy of password.prg? Is there a copy in user dmitry's temp folder? If you USE your pjx file and find the row for password.prg, what is its path?

Less likely... but is your exe huge? If so, is the virus scanner locking and preventing read of the next file that happens to be password.fxp, and/or what are your foreground/background memory settings?
