Multiecuscan

Hello,
I am new to the forum, I accidentally updated to version 5.3, for which I do not have an active license and I would like to go back to version 5.2 for which I paid the license.
Can you tell me how I can solve this problem?

I think you can just reinstall V5.2.

See: https://www.multiecuscan.net/ReleaseHistory.aspx

There you will find V5.2. Just run the installer program without removing MES.

if you still have issues then contact MES Support.
