Question

Can't get free trial licence

Hi everyone,

I am trying to activate a trial license for PTC Mathcad Prime 10.0.1.0 from Express, but I am unable to obtain the license.

I successfully logged into my PTC account and completed the License Wizard. However, when I click "Acquire License", I receive the following message:

"Error in License Processing. Please contact PTC License Management."

No additional details are provided.

I am using Mathcad Prime 10.0.1.0 on Windows and trying to activate the free trial version. I have already verified my email address and can log into my PTC account without any issues.

Has anyone experienced a similar problem?

Any help would be greatly appreciated.

Did you try activating a trial licence from the newest version, Mathcad Prime 12.0.0.1? The trial licence is designed to be for the latest version.

Thank you for your suggestion.

I was unable to install Mathcad Prime 12. The installer extracted successfully, but then crashed immediately with a setup.exe / KERNELBASE.dll error before the installation window appeared.

However, I installed Mathcad Prime 11 instead, and the activation worked successfully. I was able to obtain and use the free trial without any issues.

Thank you for your help!!

There is no “trial license”.  You download a new version of the software for “trial” and it works for 30 days.  After that you’ve got Express, all the “premium features” have been stopped; once you save a file they all are disabled.  (You can still read a new file with premium features and see what they do, just DON’T CHANGE AND SAVE it.  At that point you have a fairly capable piece of software for free, just with an annoying add for a new version of software.

Downloading a trial of a newer version (as suggested) used to enable the earlier versions of the older software again.

You’re mostly correct (especially the purposefully annoying advertisement for buying a paid version), but there definitely is a trial licence that is generated when you go through the “Acquire License” workflow from the “Get License” wizard.

It’s possible (but not advised) for people to download and install Mathcad Prime and never acquire a trial licence (so they never try Mathcad Prime with premium features). Only with the presence of this trial licence and pointing to the file in License Configuration in the Options do you get the 30-day trial.

This is apparently something that has changed since I last downloaded a new version, the new version was always fully functional for 30 days immediately. The same license also reinvigorated the older versions to full functionality for the 30 day duration.
