Hello Petr,

Thanks for posting in the group.

Based on my experience, you could check the following:

1) Is the unmanaged C++ dll a debug build that needed some debug dependency files loaded on the test machines?
Please get a release build of the dll and test again.

2) Where do you put the C++ unmanaged DLL? Please put it in ASP.NET web application bin directory or system32 direcotry
to see if the problem is still there.

3) Please download filemon and regmon from www.sysinternals.com to see which file is "access denied" or "not found" when
called from asp.net.

Hope it helps.
