Cannot install CTM

When i tried to update to a new baseline the CTM wouldnt get past a certain point without freezing up. Got that all cleared up. I did an unstall and tried to re-install and got the following error “A critical subsystem required for the proper functioning of the product is not active. This usually happens with an incomplete installation. Please re-install the product and try again.” Evadentally the uninstall did not delete the hidden partitions? or what ever they are and now I am in an endless loop of not being able to install CTM. Help

Maybe the tool mentioned in this thread could help: https://forums.comodo.com/empty-t59540.0.html;topicseen
You need to ask for it there.

No help or answer from there :-[ :-[
