A new Post Configurator post processor was developed for NX11.0.2 running on Windows 10. When this post was moved to another NX11.0.2 installation running under Windows 7, the post will not run. NX reports errors in the log file:

Solution
This is related to a missing vc redist package on the Windows 7 system. Due to the end of support for Windows 7 from Microsoft, backwards compatibility from Windows 10 to Windows 7 has not been validated.

This means if the post is developed on Windows 10, there are no issues because the vc redist files are the newer ones. By default, Windows 7 has the old package which is not supported by the newer tbcload version.
The Windows 7 system needs to update the "x64 vc redist" package from Microsoft download site:
