The 64-bit label is the operating system, not the version of MPC-HC. If you installed the 32-bit version of MPC-HC, then that is what you have.
So there is no way to "install" and use madVR on x64 bit 8.1?
32bit version with a 32bit player under 64bit OS.
It's exactly as Shintai says. Install MPC-HC 32bit and MadVR, and you're set. You do not need a 32bit OS.what do you mean? i download the 32 bit version, but it doesn't work. Do i have to use 32 bit OS?
