32-bit binaries don't generally know anything about 64-bit Windows (registry, folders, ODBC, etc) and will resolve to (be redirected to) Wow6432Node for registry reads and writes. That is the 32-bit registry locations. On 64-bit Windows the System32 folder is the 64-bit location and SysWOW64 is the 32-bit location, as unintuitive as it sounds.

I'm running from downloaded binaries (which seem to be 32bit). Could there be some MS magic going on where using 32 bit binary (and hive) results in resolving to Wow6432Node? -----Original Message----- From: Demian Brecht Sent: April-04-12 11:55 AM To: 'Ryan Boggs' Cc: nant-users@lists.sourceforge.net Subject: RE: [NAnt-users] FW: readregistry issue Thanks for the follow up. I had included the hive in one of my many variations in trying to get it to work (it defaults to "LocalMachine" according to the docs, so I assumed that I wouldn't need to set it explicitly). According to regedit, the path is correct: HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.7\InstallPath. I've now tested this on two 64bit machines and both fail with the same error. I also tried it with a nightly build and the error message was a little different: Registry Path Not Found! - key='SOFTWARE\Python\PythonCore\2.7\InstallPath\';hive='Microsoft.Win32.RegistryHive[]'; This message concerns me a bit.. Do I somehow explicitly have to set the hive to be 64bit?

I am not sure if the reg path is different on a Win64 system for Python.
