Could you point what is causing this .FLL error under certain conditions?

Hi Experts

Could you point what is causing this .FLL error under certain conditions?
I guess it's due any VFP7memory issues, could it be?

	Set Library To vfpcompression.fll Additive

Open in new window

The same code perfectly runs at my PC but not always runs at an user's  PC.
The .FLL had been renewed with a perfectly one. So a .FLL corruption like the messages suggests is remotely true.

Thanks in advance.

There are several dependencies of this FLL about C runtimes. One of them is MSVCR71.DLL, which also is needed for a VFP9 executable, but another one is MSVCP71.DLL

Especially the second MSVCP71.DLL might be missing or not found along paths known. If that changes the error can happen sometimes and not always.

You better always keep runtime DLLs at the same place as your EXEs and FLLs, then this can't happen.

You can also check missing DLLs with dependency walker: http://www.dependencywalker.com/
Just don't be tempted to copy all system DLLs into your application folder, dependencies on kernel etc. are fine with the Windows system DLLs at where they are.

Bye, Olaf.

Hi Olaf

Really it must be the ausence of MSVCP71.DLL as I checked.  

Amazingly that under unknown circunstances this ausence doesn't prevent the compression.

The user had received a system actualization and will reply the success next hours.
