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 [url]www.sysinternals.com[/url] to see which file is "access denied" or "not found" when
called from asp.net.

Hope it helps.
