Can I use the same registration key at my second/home computer?
Yes. You can use your registration key to install SAM on as many computers as you like.
If you are using SAM in a laboratory or classroom setting, please [url=mailto:sam.support@nrel.gov?subject=Installing%20SAM%20in%20a%20computer%20laboratory%20%5Bfrom%20SAM%20Support%20Forum%5D t=_self]contact us[/url] about installing SAM on multiple computers.
Best regards,
