error" An unhandled exception occurred on the dispatcher thread"

[HG_8354506]

I have installed the software successfully but cannot run it. As soon I open the program, I get an error" An unhandled exception occurred on the dispatcher thread"

There's a file named:

"MathcadPrime.exe.Config" 

On the path 

C:\ProgramData\PTC\Mathcad Prime

Delete it, or rename it if you're unsure, and then start Prime again.

Prime will recreate the file.

Success!

Hi There,

HI Luc, @LucMeekes 

I have tried the following fix which was suggested earlier but that only allowed me to enter the license information.

"""""""There's a file named:

When I open Mathcad prime 6.0 still comes with same error. I have also attached a log file as well

I am  assuming that this is not compatible with Window 10 2004.

Prime 6 sure runs without problems on (m)any Windows 10 system:

Are you sure you deleted the "MathcadPrime.exe.Config" file?

If this still fails, then you may need help from PTC support ...like @VipulT .

Success!

Hello @HG_8354506 

Try renaming the folder PTC to old_PTC in the location " C:\Users\%username%\Appdata\Local" and then launch Mathcad as Administrator. 

I hope this helps.

Thanks,

Vipul

@VipulT  I have already tried this bit it didn’t resolve the issue.

@HG_8354506,

Kindly perform the below steps 

·         Rename the file MathcadPrime.exe.Config to old_MathcadPrime.exe.Config  in the location "<C:\Program Data\PTC\Mathcad Prime>" 

·         Rename the folder PTC to old_PTC in the location " C:\Users\%username%\Appdata\Local" 

·         Clear temporary files on machine 

·         If the above instructions fails to resolve the issue, uninstall the application, reboot the machine and reinstall Mathcad Prime 

·         Alternate workaround is to copy Mathcad Prime Folder from the location C:\ProgramData\PTC from a machine on which Mathcad Prime is up and running and paste it to the                  same location on the machine having issue. 

·         Check MSXML 4.0 SP2 Parser and SDK

·         Update .NET framework 

Also, confirm whether the issue is user specific or system specific. To confirm this any other user can login and check if Mathcad is working fine or behaving in same manner 

Thanks,

Vipul
