in thread access 64bit registry from 32 bit Perl

I had a similar problem and solved it like:
use Win32API::Registry qw(:ALL); ... if( RegOpenKeyEx( HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Cryptograp +hy", 0, KEY_READ|0x0100, $key ) ) { RegQueryValueEx($key, "MachineGuid", [], $type, $nodeId, []); RegCloseKey( $key ); }
The point is 'KEY_READ|0x0100'. From http://msdn.microsoft.com/en-us/library/aa384129%28VS.85%29.aspx:
#define KEY_WOW64_64KEY 0x0100 Access a 64-bit key from either a 32-bit or 64-bit application.
