Overview
Enter your key to activate VEFmusic Pro on this site and receive the updates. The license is tied to the address of this site.
Without an active license, Pro keeps working but gets no more updates. A short outage of the license server blocks nothing: a 14-day grace period applies.
Updates
Updates are manual by default: you are told, and you decide. “Check now” checks and installs in one click. An “Automatic update” checkbox switches to silent installation instead.
Every update is checked by cryptographic signature before it is installed; if the check fails, it is cancelled with a clear message.
Version history
Each row of the version history has a button: “Update to this version” for a newer one, “Roll back to this version” for an earlier one. The exact signed file published at the time is reinstalled, with the same guarantees as a normal update. Your settings and your sales data are never touched.
