Hi All,

I have set the Registry value in the windows x64 machine at a location say
HKey_LOCAL_MACHINE\\SOFTWARE\\Rakesh\\Test
at the upgrade time when i want to open the Registry at this location using the RegOpenKey method (in a customAction) then it does not return error success.
When i see the message description then it only say
Operation completed successfully.
here is the code snippet that i am using...

static char* szKey = "SOFTWARE\\Rakesh\\Test";
HKEY hKey;
if(RegOpenKey(HKEY_LOCAL_MACHINE, szKey, &hKey) == ERROR_SUCCESS)
{
......
....
}else{
LPVOID lpMsgBuf;
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
GetLastError(),
0, // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL
);
// Process any inserts in lpMsgBuf.
// Display the string.
MessageBox( NULL, (LPCTSTR)lpMsgBuf, LError, MB_OK | MB_ICONINFORMATION );
// Free the buffer.
LocalFree( lpMsgBuf );
}

Same code is workin fine on windows 32 bit platforms..

Any body have any idea please advice me...

Thanks in advance.

Regards,
Rakesh

Not sure if you got the solution already, just if not ... WOW64 performs redirection on the filesystem as well as the registry. This redirection is done when a 32bit app calls an API reffering to either the filesystem or registry of the 64bit machine.

Hope that helps.
