Re: SysWOW64 folder
Check the below method that uses Wow64DisableWow64FsRedirection to disable file system redirection so that a 32-bit application that is running under WOW64 can open the 64-bit version of Notepad.exe in %SystemRoot%\System32 instead of being redirected to the 32-bit version in %SystemRoot%\SysWOW64.
#define _WIN32_WINNT 0x0501
#define NTDDI_VERSION 0x05010000
HANDLE hFile = INVALID_HANDLE_VALUE;
PVOID OldValue = NULL;
// Disable redirection immediately prior to the native API
// function call.
if( Wow64DisableWow64FsRedirection(&OldValue) )
// Any function calls in this block of code should be as concise
// and as simple as possible to avoid unintended results.
hFile = CreateFile(TEXT("C:\\Windows\\System32\\Notepad.exe"),
// Immediately re-enable redirection. Note that any resources
// associated with OldValue are cleaned up by this call.
if ( FALSE == Wow64RevertWow64FsRedirection(OldValue) )
// Failure to re-enable redirection should be considered
// a criticial failure and execution aborted.
// The handle, if valid, now can be used as usual, and without
// leaving redirection disabled.
if( INVALID_HANDLE_VALUE != hFile )
// Use the file handle
