I have a portable license. Second installation on a device does not work.

Question

I have a portable license.

I registered it for device 1 and it worked. Then I unregistered it for device 1 and registered it for device 2. This also worked.

But now I want to register it for device 1 (I unregistered the license from device 2) again, it accepts the keycode, but it does not work.

The same with device 2.

I have used the original keycode for the license creation.

What is the problem?

Answer

The original keycode is only for the first creation of a device depending license keycode.

When you unregister the license on the device, you get a new keycode.

This new keycode is now the keycode to create the next device depending license keycode.
