My computer crashed but the hard drive in which Solidworks 2013 loaded is working. Now it is possible to install the hard drive in another computer as secondary drive and work with Solidworks it is standalone license.
Depending on what caused the crash, switching the drive to another may work but I would expect there would be a problem with the SW activation. If that is the only problem, your SW reseller (VAR) would be able to help.
I'm afraid there would also be problems with internal references possibly to the crashed computer. The safest would be to reinstall SW after installing the drive in the new computer.
I would recommend to free the license off that hard drive, since it is still working it should be fairly simple. Reinstall and reuse that license.
Putting it as a secondary drive should bring some REGEDIT errors to show up, not only external file locations issues. It would be a huge head ache IMO.
License is assocoiated or tied in the hard drive, so even you will use the hard drive in other computer the solidworks installed in that hard drive won't be used so if your motherboard is broken then call your VAR to release your license from that Hard Drive so that you can use in other machine.
