Hi,
i was trying to upgrade from 3.0.0 to 3.0.1 by pointing maxwell_3.0.1.0_win64.exe to my maxwell install dir, but i received an error :



I then uninstalled maxwell 3.0.0 by preserving the license and tried it again, but receiving the same error messag yet.

How do i have to proceed ?

Regards,
Frank

Right click installer>Run as administrator.

Do this always, for any update or new install. Do it even if you are already logged in as admin.
