--- Comment #17 from Brendan McGrath brendan@redmandi.com --- Actually - it turns out there's already an easy way to check the registry values: wine reg query 'HKLM\Software\Microsoft\Cryptography' /v MachineGuid wine64 reg query 'HKLM\Software\Microsoft\Cryptography' /v MachineGuid
On a fresh wine prefix - you can see the 32-bit wine (which is how the Launcher runs) vs. the 64-bit wine (which is how the client runs) get two different values.
It seems you need to add 'Wow6432Node' to the registry path to get a consistent value with wine64: wine reg query 'HKLM\Software\Wow6432Node\Microsoft\Cryptography' /v MachineGuid wine64 reg query 'HKLM\Software\Wow6432Node\Microsoft\Cryptography' /v MachineGuid
My guess is they are suppose to be the same. But I'll investigate and raise an issue (or submit a patch) with wine.
