Cura install error "unhandled exception in script"

I've tried installing twice now, and when i try to run the app I get the same error message. Anybody know how to solve this issue? Thank you in advance.

Sounds like your likely on a older version of windows?

 

Make sure you are on supported version: https://support.ultimaker.com/s/article/1667337917781

Is this an error during the installation process, or when you try and run it for the first time? It looks like the latter.

I would suggest:

1. Use an uninstaller program designed to search for and clean up leftovers (I like Bulk Crap Uninstaller, free and open source) to uninstall any Cura installations you might have and clean up the leftovers.
2. Delete the installer program you have and download it again (in case it's corrupt or something).
3. Instead of just running the installer, go to the folder it's in, right click on it and click Run as administrator. The installer will usually ask for admin rights anyway, but this way you can be sure it does. Then just go through the install as normal.
4. Do whatever ritual you have that brings luck and open Cura.

Its an error after installation when I try to run it. I am on an older version of windows so I will address that and see where it gets me. Thank you for the replies
