This problem started on my desktop … every time I click on an email I get warning that mcou.dll cannot load. I tried turning off and re-starting the mail security option in KTS, but that didn’t resolve. I found this thread which is now marked as closed. It references Windows 10 and did not work for me.
On my windows 7 system, after each ADMIN cmd entry, I was told the mcou.dll file could not be found (yet it is in the root folder of /Kaspersky Internet Security 21.2/. I posted this question on that thread, but thought I should start another thread given its CLOSED status.
On my laptop, this problem started a week ago. I was able to resolve by uninstalling and reinstalling KTS. I would rather not do that if there is an easier solution. I actually have a backup copy of the mcou.dll on my E: drive.
I tried to merely copy/paste into the C: location but was told I needed system permission to do so.
Perhaps there are other posts with the solution, but many posts seem to be in a language I cannot read. TY.

Without valid fix responses and TOO much time trying to do an “easy fix”, I have uninstalled Kaspersky Total Security, saving my license. Then reinstalled. Problem gone. Not totally confident in this fix, as the program was working fine for years until, I assume, some automatic update broke it. Restore point created after fix so I can roll back to this state. Thank you to those who tried to help.
