(Not sure if this is the right section of the forums to ask this)

I've been developing on a Mac and I recently bought a Windows 7 computer. I would like to do testing on IE7 and IE8 but it appears that these versions of Internet Explorer can't be installed on Windows 7. Can anyone confirm this? And if this is true, what do you guys do to test on these old versions? I know that Adobe has something where it can simulate them (all the way down to IE6), but I'd like to do it using the actual browsers if possible.
