Valentina Studio Single and Valentina Studio PRO are licensed for deployment on a single operating system. If you order Valentina Studio Pro for macOS, that license will only work under a supported version of macOS.

• Use the RENEW option. Go to the store product page for Valentina Studio PRO and select RENEW. This will issue a new license of the OS version you select from date when the order is processed.
• Upgrade to Universal. Go to the store product page for Valentina Studio PRO Universal and select RENEW. This will issue a new license that will work on macOS, Windows & Linux systems, licensed for a single user.

Once a license is issued, it cannot be changed at a later date except through the two options above.
