Couldn't open the zproject for M200+ printer - Z-SUITE 2.26.0

Two weeks ago my Z-SUITE 2.26.0 started to have problems with the opening zproject files.

The same thing has happened to my colleague after a week or two.

It is very odd because it has worked very well for some time. Recently Z-SUITE refuse to open zproject for M200+ printer. It doesn’t have a problem with opening zproject for M200 printer.

I restarted my computer, deleted and reinstalled the application etc.
Then my support team tried to find the cause but we failed.
The only solution (and I am not happy about it) is to open the Z-SUITE on another user in Windows (guest mode) - btw I work on Windows 10. Then all the zproject work.

Could you help me with this issue?

Kind regards,

Hello Martyna,
