Hi Robert,

I built and ran your program with no problems on my system with CVI 8.0.  When I put a copy of version 7.1 of cvirte.dll next to the executable, I got errors similar to yours.  The only reasonable cause for this behavior that I can think of is that you must have an older version of the runtime engine dll somewhere on your system.  Windows searches the following locations for dlls in the order listed:

1. The directory where the executable module for the current process is located.
2. The current directory.
3. The Windows system directory.
4. The Windows directory.
5. The directories listed in the PATH environment variable.

You have already verified that you have the correct version (8.0.0.273) of the dll in the Windows system directory, so that leaves only the first two options.  Are you sure that when you copied the files over to your laptop, you didn't also copy over an older cvirte.dll that may have been in the same directory for whatever reason?  I apologize if this seems obvious, but it seems to be the most likely explanation.

I will be unable to respond until January, but if you have any more info, please post back.

Happy Holidays.

Hello Luis and Mert,

Thank you very much for your help. The problem all along has been exactly what you said - an older version of cvirte.dll (for CVI 7.0) which was in the directory of the application I had copied from CVI 7.0 to CVI 8.0. After I renamed the older version of cvirte.dll the application worked. This was something I should have caught.

Anyway, thanks again for the good work.
