Although I posted this sometime ago , my problem still occurs 100 % with the same message as above, I can't use the Reg cleaner part of CC. Currently I'm using CC v3.23 .1823

Thanks for the link Alan ,it actually did not solve anything for me , I am a moderate windows user , so exploring kernel issues is out of my league ,

Cheers again

I seemed to of resolved this myself sort of .

By unchecking Unused File Extensions from the registry scan I get no errors.

If kernel issues are out of your league,

then an accident with a registry cleaner may leave you floundering out of your depth.

Perhaps you should leave the registry cleaner alone.

I never clean the registry unless I have a special reason,

such as checking whether all traces of an application were removed when it was uninstalled.

this is one of the most important registry suggestions ever, for more see my signature
