Hello,

I'm a Linux/wine Radiant user (that's my primary radiant host).
I own a single license and I try to keep using it there, although I always tried to keep the wineprefix as clean as possible - therefore before any Radiant installation I purged the old one, including old registration data. Moreover, as I try to contribute (occasionaly) to wine appdb/bugzilla, clean wineprefix (preferably created after each wine update) is a must.
I assume some registry keys should be exported and imported to new wine prefix to keep the activation, on the other hand I don't know what other PC properties Radiant rely on, they might be different in new, clean wineprefix.

What do You recommend, apart from using Radiant licensed Radiant in a stable, not updated wineprefix, and keeping experiments, debugging and research in a different sandbox?

Hi,

The activation code is stored in registry.
If you activate the license as a user, the code goes to HKCU/Software/Medixant/
If an admin account is used to activate RadiAnt, the code goes to HKLM/Software/Medixant/
Activation code is tied to a specific hardware ID (based on RAM, CPU, Network, HDD). So if the hardware configuration reported by Wine to RadiAnt is changed, reactivation will be required.

So If I don't change any of the hardware the activation code should remain the same even in clean wineprefix?
I mean - is there any randomness in the code, or it should be regenerated and remain the same at the same hardware, therefore more frequent activation could potentially be possible?

Yes, if hardware is the same, then the activation can be performed on a clean system without any issues again and again.
