If the user has changed their username after the authorization key has been created, then GetUserName will return the new username which can't decrypt the key. The username at the time of authorization should be stored at `HKEY_CURRENT_USER\Software\\Adobe\\Adept\\Device`, which we first attempt to read before falling back if it doesn't exist.
Actions like reading the registry and serial number were being done in python even though the final decryption was done in wine. This commit moves all windows logic except architecture detection into the exe ran under wine to simplify the architecture.
