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.
