quartus Launch simulation library compiler cant find the questa executable

Some more information:

The reason I thought I needed to compile libraries is because the simulation cant find the libraries for fiftyfivenm_ver (which I assume contains the MAX10 FPGA 55nm part). According to the quickstart guide, I shouldn't need to compile those, it is done automatically--but that does not appear to be happening. Therefore, I tried to compile the MAX10 libraries using the Launch Simulation Library Compiler, but then I run into the problem where it cant find the executable (I see the vlib executable in the questa bin location).
