I have browsed the forum prior to posting this, and although have seen some others with the same problem, a solution did not seem apparent; I may have missed it.
OS: Windows 10.
After upgrading from Cubase Artist 9.5 to Artist 11 just days ago, anytime an existing or newly saved .CPR file is double-clicked it will not open Cubase 11.
It was trying to open 9.5, so I uninstalled it.
Now the files are not associated with any program.
Cubase 11 runs fine as far as I can tell so far, and I am able to load existing .CPR files once the program itself is open.
I have tried manually setting the associations in Control Panel, but they do not take hold.
I have tried right clicking on the .CPR file icon (presently blank) and trying to set it to “open with” and “always use” Cubase 11, but this is rejected as invalid in trying to open a product not currently installed.
A few screencaps attached.
A registry key mentioned in another similar topic was checked and seems to properly point to Cubase 11.
Hoping there is some way to resolve this, and appreciative of any insight.
