If possible attach a screenshot illustrating the GUI problem:

Please attach diagnostics report.

I tried, but it shows “Diagnostics did not find any errors”.

I had this problem too and managed to solve it by obtaining 2 Comodo files that were apparently missing from my Windows 10 installation, from the installation on Windows 7.

Thanks, your workaround is working on my system.

Looks to be resolved? Moving to resolved.

I’ve reported the issue. Thanks.
