I am trying to install 2015 on my computer but I can't find my serial number. I have had SW since 2006 and stayed on maintenance every year. My hard drive died so I am reinstalling everyting. I grabbed my 2015 cd and started the install, but I do not have my serial number written down anywhere. I thought it would be in my customer portal somewhere but don't see it. Looked in MySolidworks.com also with no luck. I know I can go ahead and install as a trial and then call my VAR on Monday but I guess I'm a little surprised that I can't find it in my customer portal. Maybe this is a safety thing in case someone hacked my portal?
