Mathcad Prime 12 Trial Activation Failed – “Maximum Number of License Requests” After Server Errors
Hello,
I finally managed to install and run PTC Mathcad Prime 12 after solving multiple installation issues.
At first, the application would not start at all and crashed with the following error in Event Viewer:
"Cannot locate resource 'worksheetresources.xaml'"
The issue was related to the Windows display language. After changing Windows from Polish to English and reinstalling Mathcad, the application now starts correctly.
However, I now have a licensing problem.
When I try to activate the 30-day trial, the License Wizard first showed several "Server Error" messages. After multiple attempts, I now receive this error:
"You have reached the maximum number of license requests available for your product type."
As a result, Mathcad only works in Express mode and I cannot activate the trial license.
Could someone from PTC please:
- reset my trial activation limit,
- assign a trial license to my account,
- or provide manual activation instructions?
I would really appreciate any help.
Thank you.
