Mathcad Installation

Not able to install Mathcad 11.0 in new computer (Replacing old computer). Cant find download link and also will need help transferring license.

I'm trying to find out what was changed or fixed in datecode 11.0.1.0 compared to 11.0.0.0. If there is a summary of changes/fixes on the website someplace, I haven't been able to find it. I support our company's users and would like to be able to tell them what is changed in 11.0.1.0 before they upgrade their installed version.

I am using Mathcad Prime Release 8.0 and Datecode8.0.0.0I want to add an iteration process to an ODEsolve block. It would require iterating an initial condition until two of the solutions match.

Hello!  I' a grumpy old retired curmudgeon who occasionally is asked to step in and review some of the young'uns work at my previous firm. This year, they finally gave up and transitioned from Mathcad 15 to Prime 11.  However, they use node-locked licenses; therefore The grunpu Old Man cannot remotely open their worksheets for review. If I were to install Prime 11 Express on the remote machine (or on my home machine), could I open the sheets made with the full version for review, even if all the features they may have used to make the sheet don't work for me?  (this is two questions in one, actually - remote access must be solved first...) Thanks!

I'm trying to install Mathcad 14 on my new Windows 11 PC. I've filled out the license information requested at: https://support.ptc.com/appserver/lm/mathcad/call_logger/callLogger.jsp. After filling in the information and submitting it, the page says I should receive an email response within 2 hours, and if I don't that I should contact PTC. It's been nearly 4 hours now and I've not received an email.Thank you.

I'm trying to install Mathcad 14 on a new, Windows 11 computer. I know that it is a really old version, but it works extremely well for me and I don't have funding to upgrade. That said, when I run the license set up (after installing Mathcad 14), I get an error message: The remote server returned an error: (403) ForbiddenAny help at all would be much appreciated. I'm sort of lost without Mathcad (I use it daily).Thank you.

Hi,  How do I install the XMCD/MCD converter on PTC Mathcad Prime 10? Is the only way to uninstall and reinstall Mathcad and select the extension? This is on a work computer so is there any other way to install it without doing that? Thanks 

Umzug Mathcad 14 auf neuen Computer mit Windows 11. Die Lizensierung gelingt nicht. Die Eingabe in der Tabelle mit Volume ID C: 4030-3E50 oder 40303E50 wird nicht angenommen. Auch die versuchsweise Eingabe der physikalischen Adresse des Computers führt nicht zum Erfolg. Woran liegt das und was ist zu tun?

In January 2024 the license file contained following INCREMENT blocks: INCREMENT MathcadPrime INCREMENT MATHCAD INCREMENT 254 INCREMENT 255 INCREMENT 256 INCREMENT 257 Today the license file contains following INCREMENT block, only: INCREMENT MathcadPrime License file belongs to old permanent locked Mathcad license bought in the distant past.   Can someone explain it? Maybe @DJNewman?

nu reusesc sa obtin perioada de 30 de zile gratuita la Matchadprime 11. Am nevoie de o licenta. Am primit pe email dar e doar un pdf si nici nu il pot deschide. Sau poate imi trebuie un key product de 22 de caractere care sa pot activa perioada de 30 de zile gratuita.

I have tried multiple times to download the current version of MathCAD Express, but the system has never sent the promised "installation" EMail. I have requested help from sales, but no response. I've been using MathCAD since version2 in the 1980s, but lost access to the "home use" license when I retired a few years ago. I just need MathCAD now for hobby use, with no commercial or professional usage at all. The computer that the home use version was installed on is no longer functional, so I need a copy for the new computer. Most of my hobby stuff is in MathCAD15, some is in Prime 5-8. I am in your system as PJR51@live.com, formerly Paul.Rebstock@NRC.gov. The live.com account is still active, the NRC.gov account was closed when I retired. My cell phone is 240-393-3704.How can I get the current version? Can I install it on both my laptop and my Microsoft Surface?

I had to change to a new Computer because of updating to Windows 11. Content drive C: has been cloned. It is not possible to get the license again. Mathcad cannot be used. What can I do?

Hello PTC community,   Im contacting you regarding a reoccurring issue we've encountered with a license on a specific Host,   Since 25.08.2025 we installed Mathcad License(Prime 6 which is compatible with MathCAD 15) Locked version on our host.    The license activates the software and works as intended for couple of days, after that it's getting deactivated and has to be activated again (Activated 3 times already). We've followed the procedure as shown in PTC Knowledge Base and it has worked successfully on multiple other hosts. Only on this case we encountered this issue.   Kindly advise how to proceed & let us know if more information is needed.   Best regards

I have an old copy of Mathcad 15 and Prime3.0 installed on a Windows 10 computer which was purchased 2/8/2014 . I need Windows 11 licenses for both as I purchased a new computer.

I am using Mathcad Prime Release 10.0 and Datecode10.0.0.0My company uses Python scripts to extract Mathcad Prime data to Excel spreadsheets. The Python code uses the MathcadPy library to extract data to the spreadsheets, but I am continually getting errors when running the code. I have also seen the error popup when running Mathcad Prime normally.We create a folder structure of Mathcad Prime files, using relative links to point to the folder/file at the next level up. We have a number of Mathcad sheets in the same folder and they all point to Mathcad files at the directory above , to make a make-shift library of electrical parts/parameters for our application.I will randomly see the error pop-up when accessing these files. It is also random, and there is no predictability to the error popping up.Here are the errors that I faced"An unhandled exception occured. See .log file"Exception data:System.Exception: Lisp applying: CallNodeCallback {global} to Engine.NodeCallback, 1419, NODE_READ

i have been a long time user of MathCad, strongly prefer the old, non prime versions.  Thinking of trying Prime once again, in case MathCAD 15 no longer can be made to work.  When to activate a newly downloaded, properly assigned locked licence, Prime does not seem to have an activated licence.  For example the watermark is there, the activate button is live, and not all functionality is available.  I'm not sure what to try next.  I've verified the MAC ID, downloaded new licence files a few times, tried on Windows 10 and windows 11 PC (of course properly assigning the MAC is in licence manager).  I also opened a ticket for support, that I have paid for for years and years and years, and have enjoyed no reply so far (about a week of waiting). Any tips?

I have Mathcad 14, working fine till now. I was bound to reinstall the PC, but now I get error in licensing the mathcad 14. "Unexpected Error. The remote server returned an error: (403) Forbidden."I did not get any time limit when I bought Mathcad 14, so I should be able to continue using it. It is only for occassional private (academic) use.
