Each spreadsheet comes with 1 license key. The number of domains (i.e. computers) a key can support depends on the version of the spreadsheet you purchased:
- Light Version: does not require any license key
- Advanced Version: supports 1 user with up to 2 computers per key
- Pro Version: supports up to 5 users with up to 10 computers per key
Check out our article on how to generate my license key if your license key has not been generated automatically after purchase.
