Is version 1.9 a 32 bit update? Shouldn't it be 64 bit?

I had installed the VSTs that came with the MPC Touch on my Mac as well as windows computer and had used them the other day but now they're not showing up in the MPC software (the Riser, mini-grand, and db-33 are not showing up) on my Mac but do show up in Reaper. I clicked on the About MPC to verify the version number and it says 1.9.0 (32-bit), I thought it would be 64-bit. If it's 32 bit then wouldn't that limit how much ram you can utilize within the MPC application? I may be way off base, can someone correct me if I'm wrong.

You should have both versions. I think it automatically installs both but not 100%sure...you may need to select 64 during instal

Both are installed But only the 32bit version gets a Desktop icon by default.
In the installation only the plugins' platform can be selected.
