Re: [Condor-users] Issue on Windows 64 and querying the registry

["Michael McClenahan" <michael.mcclenahan@xxxxxxxxxxxxxxx>]

It isnt too hard to work around it and gain access to the real (64bit)
registry from a 32bit process. I use 32bit perl processes to often read
the real 64 bit registry.

Google for "KEY_WOW64_32KEY"

Pass in this flag whenever you try and open a registry key to get access
to the real 64bit reg.

Check out the MSDN article "Registry Key Security and Access Rights"
http://msdn2.microsoft.com/en-us/library/ms724878.aspx

KEY_WOW64_32KEY (0x0200) 	Indicates that an application on 64-bit
Windows should operate on the 32-bit registry view. For more
information, see Accessing an Alternate Registry View. This flag must be
combined using the OR operator with the other flags in this table that
either query or access registry values. Windows 2000:  This flag is not
supported.

KEY_WOW64_64KEY (0x0100) 	Indicates that an application on 64-bit
Windows should operate on the 64-bit registry view. For more
information, see Accessing an Alternate Registry View. This flag must be
combined using the OR operator with the other flags in this table that
either query or access registry values. Windows 2000:  This flag is not
supported.

More information on this is at http://support.microsoft.com/kb/896456

  'cmd.exe' launched from a 32-bit app ( such as the Condor daemons)
only sees a 32-bit view of the world.
