I have a perpetual license to install MATCAD 15. But since the file was attached to an MSN hotmail email, it disappeared along with the hotmail. How can I reinstall MATHCAD 15?
I should think the license file would still reside on your PC, since Mathcad cannot work with a license file residing in Hotmail...
Success!

Mathcad 15 works on two of my computers, in one of the Mathcad 15 folders there is the license.dat file from 2015. I copied it to a pen drive and used it on the new computer, but Mathcad does not recognize it. Where can I find the "good" license?
In general the license file is tied to the MAC address (unique ID of your network interface) of your PC. So a license file for one PC does not work on another PC, but that should give another error message.
Here the message is that this license had expired (some 9 years ago).
Success!

I solved my problem! Best regards and thanks anyway.
Hello everyone,
it happens to me that, after trying to install a software for transferring large amounts of data from the old computer to this new one. but without success, mathcad no longer works. Something has changed the hostid. I go to ask for the license again but PTC gives me error 403. And now what do I do? Who can help me recover the license?
Only PTC license support group can help with a new license.
