Assignment of Mathcad 14 License

JB_1288282 — Fri, 12 Dec 2025 11:13:02 GMT

I have been using Mathcad 14 for many years. After upgrading to a new PC, I tried to reinstall Mathcad 14, but the licensing process failed. The website returned the following message:

The remote server returned an error: 403 Forbidden.

Could you please assist me in resolving this issue?

Support for Mathcad (all versions) and Prime (up to and including version 6) ended a couple of years ago, see here.

For licensing you need to contact PTC support directly, as this forum is for and (mostly) by users of the software.

To reach PTC support try the following links:

"Mathcad Contacts": https://support.ptc.com/support/mathcad_contacts.htm
"Mathcad Installation & Licensing Support Center": https://support.ptc.com/support/mathcad_supportCenter.htm

Success!

RESTRICTED

Hi,

Yes, I got help and reinstalled Mathcad on my new PC. But it was necessary to pass by the WEB page which asks me for the installation for a single station. And with this WEB page I finished the installation.
Thank you for your help

Regards

How did you bypass the Website? I've got the exact same problem and I'm getting zero help from PTC.

That link gets a new license, which installs flawlessly, and says it is valid, but the first time you try running Mathcad, it says it is invalid and you are back to the beginning without a working license.
