Starting with PBP: how to restart with PBP today

[CipOne]

Thanks to everyone for the help and I update the post:
I finally managed to repair Windows XP, blocked since 2016, containing PBP (PBPX 3.0. 7.4) and MicroCode Studio (MCS+ 5.0. 0.5), which now work perfectly.
Now I intend to install the entire environment (PBP, MCS, MPLAB) on the Notebook with Win 11 pro.
The internet functions work (tracert and ping), but of course Win XP does not allow navigation.
What is now the procedure to recover the license installed on XP?
Do I simply have to uninstall the 2 applications with the internet connected?
