Run the Uninstaller tool to remove CIS and then use .8012 in the interim if you are having issues as described in my post here:
The Containment protection is the same in the old version and the new version of CIS/CF. The certificates will be updated in the next couple of days. What you decided to do between now an then is up to you. I run CFW .8012 just fine on Win 11 and waiting for the updated certificates before installing 2025 again.
