32bit apps can query the 64bit registry, using the appropriate security and access rights options such as KEY_WOW64_64KEY (0x0100). Similarly KEY_WOW64_32KEY can be used for 64bit apps to read/write the 32bit registry without having to have knowledge of how the Wow6432Nodes are arranged . These mean that a 64bit aware app, whether compiled as 64 or 32 bits, can access the alternative view of the registry. http://msdn.microsoft.com/en-us/library/ms724897(VS.85).aspx http://msdn.microsoft.com/en-us/library/ms724878(VS.85).aspx For example if you have both 64 and 32 bit copies of Python installed then a Python app running under the 32bit copy of Python can query the location of the 64bit copy of Python using code like: key64 = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, "Software\\Python\\PythonCore\\2.6\\PythonPath", 0, _winreg.KEY_READ + 0x0100) _winreg.QueryValue(key, "") C code can do similarly. ---------- nosy: +Stephen.White _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6792> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
