-- Posted by Mediocre at 5:54 pm on July 6, 2008 I want to have multple versions of various browsers on hand, for website compatibility testing. How can I ensure that my old version will not be overwritten when I install the next? (In particular, I'm looking to keep IE 6 while adding IE 7...) -- Posted by Gabriel Gray at 5:59 pm on July 6, 2008 Your better of using a browser compatibility program... Or an online service. I cant remember any of the free ones off of the top of my head, but the one I use that isn't terribly expensive is www.browsercam.com. A quick google search should turn up the free ones. There is one really good one out there I used to use. I just use browsercam because of the fact that it supports so many browsers. Otherwise you will have to create a virtual environment for each browser version.
