If I understand your problem correctly then you need to look at File System Redirector

The %windir%\System32 directory is reserved for 64-bit applications. Most DLL file names were not changed when 64-bit versions of the DLLs were created, so 32-bit versions of the DLLs are stored in a different directory. WOW64 hides this difference using a file system redirector.

In most cases, whenever a 32-bit application attempts to access %windir%\System32, the access is redirected to %windir%\SysWOW64. Access to %windir%\lastgood\system32 is redirected to %windir%\lastgood\SysWOW64. Access to %windir%\regedit.exe is redirected to %windir%\SysWOW64\regedit.exe.

Also there is small sample at the bottom of page if you can try that one

string system32Directory = Path.Combine(Environment.ExpandEnvironmentVariables("%windir%"), "system32");
if(Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
{
// For 32-bit processes on 64-bit systems, %windir%\system32 folder
// can only be accessed by specifying %windir%\sysnative folder.
system32Directory = Path.Combine(Environment.ExpandEnvironmentVariables("%windir%"), "sysnative");
}
