setting default version of Quartus II in Windows 7

I installed Quartus II 14.0 but I don't want to switch over to it yet. I'm still running 13.0sp1. How do I make 13.0sp1 the default so that when I double-click a .qpf file the project opens in 13.0sp...

Here's my "simple" solution, along with how I figured it out.

1. Start Quartus 14.0, and then exit.

2. Start a Cygwin shell (not the NIOS II IDE Shell version) and type

echo $QUARTUS_ROOTDIR

and that points to the 14.0 install

3. Start Quartus 13.1, and then exit.

4. Start a Cygwin shell and type

echo $QUARTUS_ROOTDIR

and that points to the 13.1 install

So, QUARTUS_ROOTDIR is dynamically set by Quartus, and gets left at the last version that ran.

Cheers,

Dave
