VFPCompression.FLL invalid data

    Question

  • Hi all,

    I`m have search internet and need MSVCR71.DLL and MSVCP71.DLL in same directory with VFPCompression.FLL.

    But somehow it will return error "invalid data" error message.

    Any advice ?

    Thanks,

    Jeff.

  • So the original error  "invalid data" is gone but now you have  "library file Vfpcompression is invalid"?

    This error points to disabled access to vfpcompression.fll or to missing/invalid msvcr71.dll msvcp71.dll. Antivirus is one possible cause.

    You have to compare files and environments on your computers. Remote desktop should show necessary data...

    Of course, you may contact Vfpcompression authors.

  • Hi Risa-CiCi,

    Users cannot install VFP 9 in the production server.

    But maybe runtime will do.

    Thanks.

  • Hi Risa - Cici,

    Same issues found but not for all zip files.

    I tried to run for second times , sometimes it will unzip succesfully. Strange.

    Thanks.

  • Does this happen when you use ZLIB directly? (http://www.foxclub.ru/sol/solution439.php)
