Ahhh! OK. Now you have to do one more thing; uninstall CR 10.5
This is a must. Else you will find next time you open the project, if it finds the CR 10.5 assemblies on the dev box, it will again use those. It will drive you bonkers.
On a deployed / runtime computer, CR 10.5 and CRVS are fine, but not on a development system.
