How Many PCs Can You Use One Licence On
One PC at a time. You can move it between machines, but it does not run on two at once.
Why
Moving to a different PC
Sign out on the old PC if you still have it
Install and sign in on the new one
If the old PC is gone, reset the device link from your account instead. You do not need access to it.
Resets
Active Premium includes one free reset per year. After that the price rises each time, starting at 1.99 euro. Signing out rather than resetting avoids using one.
A desktop and a laptop
That is two machines and needs two licences, even if only you use both.
The free tier
Install the app on as many PCs as you like and use the free tier on each. The limit applies to the Premium licence, not to the app.
What counts as a new PC
Replacing your motherboard, processor or main drive can look like a different machine. Adding memory, swapping a graphics card or plugging in a monitor usually does not. A Windows reinstall sometimes does and sometimes does not.
If you are asked to reset and changed nothing
Do not pay. Send us a message from the support bubble at the bottom right with the email on your account and we will look at it.
