[Solved] Cannot open GUI

When I rightclick on the icon in the tasbar and chose OPEN nothing happens.
After a while this popups:

Please provide more details. Did you update?

Everything is up to date !
Windows 10 and CIS !

Try to re-install. [guide]

Well, to reinstall it I must be able to uninstall it first but I cannot !

I only want to report that everything is OK now !

I went into Windows Safe Mode, deleted all the folders of Comodo.

Rebooted into Normal Mode, cleaned the registry with CCleaner, downloaded the newest CIS installer and installed it.

After I could open the GUI again but it refused to install the AV signatures.

Downloaded them manually and updated via CIS and voila: Everything is working now. :-TU
