Is it possible to run 2 versions of Hybrid (R65 & R68) on the same computer?

You can't install multiple versions of Hybrid. (they would share the tools paths etc.)
But you can use different portable versions. (not sure one can mix a portable and a systemwide install)
But when using vsViewer outside of Hybrid you need to adjust the environments of the two.
