Mathcad prime 10.0.0.0 failing to save

Mathcad prime 10.0.0.0 failing to save

Just as i thought the problem was solved it went back. I tried resetting my pc and downloading everything from scratch. I have a lenovo with windows 11 home. Everytime i try saving a document a corrupt saving page pops up. i will attach it here. Skærmbillede 2026-02-03 122031.png

It happens when i use; save as, save or any type of export.

I have tried reinstalling several times, also as administrator, and it has the same outcome.

When running the program as admin it gives 3 more seconds on the save window but inevitably it crashes again. I made sure i unpacked the download zip-file locally and not using onedrive. Also i placed the app locally. 

 

Background info: Im a danish student at Aarhus university. They supply license to mathcad prime 10.0.0.0 and is therefore my only way of downloading the program. I have got a new pc as the old one got destroyed, and now the problem is occuring. I have tried following instructions to solution finding through AI, but it has not lead me to a working solution. I have reset my pc and tried reinstalling the program several times without a payoff. IT-support at uni leads me in the direction of mathcad or PTC as they dont know enough about the program.

Hmmm, I see that your Prime 'speaks' English. I seem to see that your Windows is in Danish.

What if you run Prime in your locale?

To run Prime in your locale, start it with the proper switch. Try:

    MathcadPrime.exe /culture:dk-DK

(and hope that Danish is supported... EDIT: I see it isn't, you get English.).
The other option would be to install/switch your Windows to English....

 

Another item (less invasive than changing Windows language) you could try is about your keyboard: Do you use a Danish keyboard, then (install and) switch to English International.

 

Success!

hi Luc.

 

I tried changing the windows language to english. i still have the same thing happening unfortunately. I got a new pc today which needed to be set up. i did not download the latest software updates for windows in the settings before downloading mathcad. This actually made it possible to use mathcad and save files. but when i later downloadded and installed the latest updates from windows it crashed again when trying to save. I might suspect some compatibility issue with a windows update and the program. could this be the case?

Hi William,

That certainly could be the case. It wouldn't be the first application (not even the first Prime) that suffers from a windows update or hotfix. The strange thing though is that only you seem to be affected by it. That could be when your PC has certain hardware that requires a specific update.
I've checked that my Prime 10 (express) on Windows 11 runs and saves fine.  I've updated my Windows 11 to the latest update, the 2026-01 Preview Update (KB5074105( (26200.7705) just now, and the result afterwards is the same: runs and saves fine.

I guess you should contact PTC support and have them help you. (Note that this forum is for and by users)

 

Success!

Hey
I have the same problem. Have you found a solution?

I am also a student at Aarhus Univerity.
