While I was saving a part, this window appeared and it doesn allow me to save the part
Do you have full admin rights to this computer?
Same thing is happening to me, Please help if you know how to fix it.
In the times I have seen this error the issue tracked back to the antivirus software. What antivirus software are you running right now? Does the error go away when you disable its Real Time Protection?
I'm having the same issue, recently upgraded to SW2019 Sp2, running TrendMicro Antivirus - was running on SW2018 SP5 with no issues... Has anyone found out what this is yet?
Try clean up the temp folder.
ie delete everything in it.
Tried that, it just changed the number of the SWX folder that it found the error in within the temp directory. I've got more things going wrong now too - I enter data into the custom properties using the Taskpane tab - save the part - then check again and the properties are not being saved. I can still check entering them manually - and that will be my next step.
Failing that - I may uninstall and clean out all registry references to previous versions then start again. I suspect there are some previous hooks causing issues!
