Altera Quartus falsly says Modelsim isn't installed

问题

Installed Quartus 13.0 with Modelsim in Fedora 22 64-bit. Running Quartus in 32-bit because I get lots and lots of problems otherwise. However, I can start Quartus, create a project, synthesize it, fire up the simulation window and configure the in signals. Then, when clicking the button for launching Modelsim, it starts doing it's job, but ends up with

ModelSim-Altera was not found. Please install ModelSim-Altera which is included with the Quartus II installer, or use the Quartus II Simulator instead by selecting "Simulation > Options > Quartus II Simulator"

This is simply not true. I can start Modelsim myself by running vsim. Here follows the full output. Any suggestions to resolve this will be +1 and no suggestions which would make sense will be punished by me.

回答1:

Please check if the path to the ModelSim binary is correctly specified under Tools -> Options

I am in Windows, but hopefully the settings should be the same under Linux
