Hi Robert,
I agree with you, it can be quite time consuming to uninstall a CodeWarrior version and then make a new installation to make an update to it.
Regarding the project, I tried to run the project but notice noticed that it has no files inside the sources folder:

and it also has some linked resources which are pointing to your backup project:

You can zip the missing files and attach it here, or as I mentioned before if the project cannot be shared through the community you can send it in a case by entering a ticket NXP Technichal support.
Best Regards!
