Quartus -multiple versions on one PC

Are versions of Quartus installed as independent applications? I have 17.1 installed and now I need 15.x . Thanks.

    One note about this: if you open projects by double-clicking on their .qpf files, it may not open the version of the software you want. Adjust your environment variable (I forget which one it is) to point to the one you want to use, or be sure to open projects from within Quartus.

    Basically, yes. They would be installed in entirely different directory structures. E.G., 17.1 under C:\Altera\Quartus\17.1, and 15.0 under C:\Altera\Quartus\15.0

    I then use a command script to set the appropriate environment variables to point to one or other of the directory trees. In my case I use a shell command script: 

    #!/bin/bash# 
export QUARTUS_BASE=/cygdrive/C/Altera/Quartus/15.0
export QUARTUS_ROOTDIR=${QUARTUS_BASE}/quartus
if  ; then
  export QUARTUS_BIN=${QUARTUS_BASE}/quartus/bin64
else
  export QUARTUS_BIN=${QUARTUS_BASE}/quartus/bin
fi
export QSYS_ROOTDIR=${QUARTUS_BASE}/quartus/sopc_builder/bin
export SOPC_KIT_NIOS2=${QUARTUS_BASE}/nios2eds

    under CYGWIN on Windows 7 64b, but there are lots of different ways to do this using windows batch command files or other programs.
