Windows 10 - Everything running well then stopped, CIS will not start or install

I have been running Firewall successfully for months with Windows 10. Last night for some reason Firewall stopped running. It will not start. Error message: “COMODO security agent could not be started. Would you like to run diagnostics … .” I run diagnostics and it finds nothing wrong. When I try to run the installer to reinstall CIS Windows stops it citing that the program is not compatible with Windows 10.

Everything was working well yesterday. Anybody have any ideas about what is happening? There were absolutely no problems running the program prior to this happening. The only thing I did yesteday was install VMware Player.

I have the same issue. Its worse than Norton on my computer. And forget about uninstalling it. Only way to remove it is to reinstall Windows 10.
