11 years agoMy suggestion for managing multiple installations is to explicitly setup QUARTUS_ROOTDIR and your PATH to correctly point to the version of the tools you would like to use before you use them.
Under Linux, I keep a simple shell script to setup the environment for the indicated version. I just run it manually each time I launch an xterm when I intend to use the Altera tools.
