The download from your webpage (ccleaner - speccy - download - you’re not allowing me to enter the link here) is presently dysfunctional. It’s apparently in Albanian, and in any event its options don’t seem to work. Speccy does not appear to be installed, in the sense that it is not running and does not leave a link in the Start menu - but at the same time it is installed in appwiz.cpl and resists uninstallation there.
Try using the installer from here: Speccy - Download Builds
I guess you are not in Albania, but are you using a VPN (or other identity/digitial-fingerprint hider) by any chance?
