Why my VFP exe file cannot be launched?

I complied my program under VFP6 into an exe file in the program folder. But it cannot be launched. I believe there is nothing wrong with the code, because I just made a minor change.

The funny thing is that if I copied the file to other folders on the same drive, it works! And even more wear is that some old version VFP exe files could not be launched from within that program folder, either. I have to copy them out to test.

It only happens to VFP exe files. Other exe files are OK.

It did the same with VFP9.

Any idea what could be the problem

VFP .EXE files require the appropriate VFP runtime. It sounds like you don't have these in your Windows PATH. Note: If you compile under VFP 6.0 SP5, it won't run without the VFP 6,0 runtimes, and you may actually require the VFP 6.0 SP5 runtimes.

VFP 9.0 .EXEs are similar in that they need VFP 9.0 runtimes!

Do you mean those vfp6*.dll files

They are under my c:\windows\system32 folder. I also had a copy under the program folder I mentioned.

The thing is the folder had been working well for years until last weekend. It happens to another similar folder on the server. I doubt something is wrong with VFP engine.

Thank you for your answer.

How do I refresh *.dll files Thanks.

That is the reason! I never touched the config.fpw file. It now works after I set screen = on.

Thank you SharathMum and all for your answers! Have a nice day.
