Hi,
I have the exact same issue. (And the same product, the Multiplicity KVM version)
In addition during the product key activation it at first says "Multiplicity activation successful" but then when clicking "Next" it says directly afterwards "Multiplicity has not been activated. Please go back and complete product activation." (Translating from German here, so actual wording is probably different)

I've followed every step outlined in different posts and FAQ but am unable to get Multiplicity to properly activate.

I've tried:

• using Email and Key
• using activation via Account Login
• deleting the Multiplicity folder from "%ProgramData%\Stardock\"
• using the "cmd" command from the FAQ to apply the license
• Unload Multiplicity and start the application as Administrator

Nothing helped, the pop-up still keeps appearing.
Is there a way to tell if the pop-up is just displayed incorrectly and the product has been properly activated?
I don't want the product to suddenly stop working as I actually just swapped from Synergy to this solution as you are offering features I'm interested in.

Any other suggestions to get this solved?
The product seems to work fine, but the License Pop-up is really irritating when you know you have an active license.

Thanks,
Zillith

Hello,

Thanks, the problem is now gone,

Before your reply, I also tried using the MP Purge tool. I wonder if that also had something to do with fixing the problem.
