I would have to ask the obvious have you checked to make sure that the dll in the installed directory?

Yes, that dll is already present in installed directory.
Because it is working fine when there is Visual Studio installed.

It sounds like you are trying to use a dll that is part of Visual Studio, but not part of the standard Windows distribution. Should be easy enough to check.

"xyz" probably has its own dependencies that are not being met (and which are causing the actual error message).
