Sounds like a case of registry corruption.

Hi there,

From your description, it looks like registry corruption (as I’ve said in similar topics; incorrect permissions). Running as System is usually not enough.
I’d recommend running regedit as TrustedInstaller. Here’s a tool : GitHub - jschicht/RunAsTI: Launch processes with TrustedInstaller privilege

Hope it helps.

PS:

1. The reason why I’m not posting a complete guide is because it’s dangerous. You should use extra caution when messing with registry. You can find more info by utilizing search engines.
2. Such corruption may cause subtle issues. For example, you cannot assume that by fixing every key that is used by Comodo you will get it working. That’s why you should consider resetting permissions for all keys which takes some time depending on system performance and so on.
