Thanks. It appears to have both the 1.7.2 directory and the jar file inside.
I didn't understand what you meant by "pointing the installer". I simply downloaded to desktop and attempted to run, then got the error. Just noticed however, that the installer was trying to run against my user name vs user instance I was on (my son's). I have admin rights, so while on his Windows user login, I had to sign in w/my admid account to allow the installer to run. Noticed that it was pointing to Users/Steve/... instead of Users/Chris/... so I was using the wrong path. DOH!
Thanks for pointing me in the right direction. Appears to have installed fine now!
