Reading from and writing to Win7 64-bit registry

Krog · Post by **Krog** » Fri Dec 23, 2011 8:51 am

Hi all.

I really need to change a reg-key in the registry on my Win7 64-bit machine - but it seems that the built-in registry key changer in EventGhost only works on 32-bit systems. Can anyone point me in the right direction?

PS: I am a noob at Python.

Yours

Michael

A lot of views, but no replies.

Nevermind: Solved it myself. If you modify c:\Program Files (x86)\EventGhost\plugins\System\Registry.py line 698 from:

_winreg.KEY_WRITE | _winreg.KEY_READ

...to...

_winreg.KEY_WRITE | _winreg.KEY_READ | _winreg.KEY_WOW64_64KEY

...it works on a 64-bit Win7. In all fairness, there should be some kind of check whether the OS is 64-bit, but I don't need it in my current environment.

Yours

Michael

Just out of curiosity, after making this change, does it still work in 32bit windows? Would you mind testing?

No it will not work in 32-bit systems since it will access the 64-bit version of the registry-hive.
I think there should be a setting which you can use to remove that flag in order to access the 32-bit registry.
If you don't set it you always try to access the correct registry according to operating system.
