Question

MathCad 14 license over the Internet - Server Error

I don't have a customer number or SCN, just a web account to manage my license.

I have a version of Mathcad 14, I know it's old, but it works for what I do.

My problem is reinstalling it on a new Windows 11 Laptop. It is on my Windows 10 Laptop but after a Windows update the operating system failed and is irreparable.

 

The link I had to the Single User License is:
https://support.ptc.com/appserver/lm/mathcad/call_logger/callLogger.jsp, and it worked but after entering the product code I get this error message:

Invalid parameter values have been passed in. The application cannot continue.

 

I couldn't log a case from that screen as well.  

 

From what I'm reading MathCad license retrieval may no longer be supported.    I May have to abandon it and go to Smath Studio or some other program.

I found that I could install Mathcad 14 on my newest laptop without an older product version number and I copied those files to my resurrected  and set the registry entries but the license I had for that laptop no linger worked because by formatting that drive and reinstalling Windows 11 it changed the CPU Host ID, so that's a dead-end unless PTC .lets me update my license.

 

So the only working version I now have of Mathcad 14 is on a slow Windows 7 laptop.  But one thing I was able to do was to setup a remote desktop connection so I can access it from newest laptop.

Hello Andrew,

 

I was notified that the case was closed so I took the link to view the case viewer.  When I entered my product code to get more info I found I had 1 digit wrong.  So, that was one error I made trying to get a license. The other mistake I made was to use the dashes between the three sets of numbers/characters in the product code.  Once I corrected the product code and entered all the numbers/characters continuously I was able to get an updated license for my Windows 11 system.  So this was my error and I guess it's still possible to get a license when upgrading your computers.  So I was able to complete the license process and Mathcad 14 now works on this laptop.

Thanks for looking into this for me. 🙂
