Cannot get CS2 to work, and it won't let me reinstall it or remove it.

Question

Right this second I am so upset with Adobe I could spit!
When I try to pull up Illustrator CS2, it shows up and shuts down, badaboom.  When I try to do a reinstall, I click on the first 'continue' and it says that the install has been interrupted, and shuts down, even if I let it sit there for half an hour.  Wnen I go into Windows remove-program, Illustrator CS2 shows up, but the 'remove' option doesn't, and Illustrator 10.0, which is installed, doesn't even show.
In the past month I've had problems with Bridge, am currently having problems with PhotoShop CS4 (it won't see the pen functions for my Wacom tablet), and now this with Illustrator, and right this second a customer wants a CS2 graphic - right now!  If I could get the program to run or reinstall I could meet the requirement, however, I can't even delete it.
And plese don't tell me to spend more money to upgrade.  That's not how it should work.  I'm retired, work on an extremely limited budget, and cannot afford upgrading at this time.

Answer 1

I've reached a point where all offered alternatives seem exhausted, and I must now do a complete system rebuild. CleanSweep doesn't even do a thorough job.
I'm on record, from my purchasing history, of being a solid Adobe citizen.  However, this circumstance is, quite possibly, one of the most unacceptable that I've ever encountered.  For one, no 'app' should ever require a rebuild.  For two, no later version of another app should ever disallow reinstalling the earlier app (because I upgrade to PhotoShop CS4 I can't reinstall DreamWeaver CS3?).  Also, while this might be a 'known' problem, as a user, I don't see that highlighted in Adobe advertising as it absolutely should be.  Maybe there should be a banner on all products that says, "You MUST buy complete Suite upgrades!"
Sorry, but as someone with a fair history in software development and deployment, this is not proper.  But then I'm 'past my prime' on such matters perhaps.
