It is possible any time to

• upgrade Hard Disk Sentinel standard to Professional version (to use on same system)
• upgrade Hard Disk Sentinel standard to Professional Family license (to use on multiple computers, up to 5)
• upgrade Hard Disk Sentinel Professional to Professional Family license (to use on multiple computers, up to 5)

To upgrade, please send an e-mail to info@hdsentinel.com with the original license code and the preferred version, so we can send the details.

The price of the license upgrade is approximately the difference between the versions, so things work just like if you'd originally order the bigger package.
