I'm in the process of re-installing Solidworks, and I was wondering if the lynkoa cpm download folder was the Premium version, or if the supplements should be downloaded later?
Normally everything is downloaded at the same time. On the other hand, are you sure that the PREMIUM license is on your computer? because it is this that gives access to the complement SCANTO3D.
Have you tried to activate other add-ons that require the Premium license???
This may come from the fact that I am not subscribed to maintenance and therefore my serial number would be "expired" so Solidworks does not allow me to access Prenium obtions?
I don't think so, because if at the time you had bought a Premium license, you bought it it's yours! Only today's updates are not accessible (and maintenance of course)
I don't really see there... uninstall, reinstall!? I don't really know, sorry...
