On 64-bit versions of Windows, two rundll32.exe programs exist:

  • 64-bit: C:\Windows\System32\rundll32.exe
  • 32-bit: C:\Windows\SysWOW64\rundll32.exe

If you are trying to do this from a 32-bit program, you might need to use C:\Windows\Sysnative or temporarily turn off WoW64 file system redirection. See the Microsoft documentation.
