install / uninstall

Hi
Since a few days cis reports that the firewall ist not functioning correctly. Wenn I run diagnostics I get the message that it could not repair the problems. When I try to uninstall CIS it say it can not access CFT.exe in the installation path. I should run it from C:\windows\system32 but ther is no such file.
I reinstalled and had the same problems.
Can somebody help?
Tnanks in advance
Heinz

Thanks.
