I installed SMATH on my new Windows 11 PC. When I clicked on activate, I got this message. What do I do?


Thanks for any help.

And this is what my account indicates about my license. What gives?????



It indicates I can have it on up to 5 devices.

Since it's a lifetime license, why did it expire? It is still is active on my old Windows 10 PC.

As the error message says, the problem seems to be in the digital signature of the license, not in the license itself; maybe a signing certificate is expired, or there is some othe problem in the validation chain.

I suggest to write a mail to Andrey, as he is the only one that can troubleshoot licensing issues.

Thank you Davide.

We are already in touch with Reg Curry to find out a solution.

Best regards.
