ok we had a computer with solidworks 2015v4 that went down. We got it working but lost everything like lost windows level of everything. The subscription is expired , however we did save everything on a back up including updates before the crash. We have the disk for solidworks 2015. and I think we just call are var to get him to release the licence so we can put it back on there. In short is there a way to update solidworks with out a subscription.
When you contact your VAR they should be able to send you the last service pack that was released while you were still on subscription, but you'll need to get back on subscription to get a newer version of the software.
