Cura 4.4 error at start

Recommended Posts

Posted · Cura 4.4 error at start

Hi.

I've updated Cura form 4.0.0 and 4.2.0 to 4.4 on 2 computers and it's not starting on both. I've tried Administrator rights and Windows 8 compatibility and still nothing.

The errors shown:

 

Traceback (most recent call last):

go into directory my computer>user>(whatever your user name is)>appdata

(if you dont see appdata you need to show hidden files in that folder.)

 

now go into local and delete cura folder
then go into roaming and delete cura folder.

relaunch your program and it should work.

      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
