Piece of crap adobe reader (double install)

Ok i'm about to kill someone here, is it possible to install 2 versions of Acrobat reader, on 1 PC.

Reason is simple, at work our clients uses alot of website with PDF forms in it.

All of them have 9.5 atm (yes old version)

Now some are calling me, saying hey we changed our what ever company and the other company uses Adobe 7.0 ( yes thats right) So I install 7.0 and they call me 20min later saying but now our other site needs 9.5.

FKKKK lol exept telling the Companies to actually update their website, anything else that can save me?

Some of our computers at work have adobe professional 7.0 and reader 11. Not sure about 2 readers (professional will have reader as well though, and allows you to open in either or)
