>I hope someone has a quick answer to my problem. I am using Craig Boyd's VFPCompression.FLL library to create backups (zip files). The program works fine on 8 out of 10 computers. The error message "Library file Craig VFPCompression.FLL is invalid" on XP computers.
>Your thoughts will be appreciated. TIA

From Craig's site:

It requires the msvcr71.dll which is one of the VFP 9 runtime libraries. So, if you are running VFP 9 apps then no other files are needed, if you are running earlier VFP version then you will need msvcr71.dll installed where vfpcompression.fll can find it.


Does that help?
