Yes, the reason is that setup looks into c:\cygwin by default and if it
finds setup files there, it will use them, even when you change the
path.  That doesn't occur in the new setup-1.7.exe, but that doesn't
help with installing 1.5 after 1.7, of course.

What you should do in this case, basically:

- Stop all 1.7 processes.
- Rename C:\cygwin to C:\cygwin-foo
- Start setup for 1.5
- change the installation path to c:\cygwin-1.5
- After the installation, rename C:\cygwin-foo back to C:\cygwin
