Hi,

I was using Cura 2.6.2 perfectly here and decide to update to cura 2.7 which work until I restart my PC.

checking the error log I found this

in screen i only see loading plugins and suddenly close.

what can be wrong, if i uninstall and reinstall nothing happens even if delete teh folder of cura inside ..\users\appdata\local\

if i reinstall 2.6.2 everything work OK again

thanks for this fine software.

Uh, for some reason it can't run load the backend plugin. This usually has to do with virus scanners blocking it.
