Strange Installation Error. Need help!

[.JeT]

I've had this before, if I remember correctly, but today I started up the trial installation for the new 3Ds Max 2009. And in the middle of it all, I get this strange message. I'm no computer expert, so I have no idea what must be causing this. I tried Google but I haven't digged where deep, and it seems a lot of people get this error. Here's a picture of the install. And i strongly doubt it has something to do with Vista. Can someone help me??

Seems to be looking at the registry.

Do you fulfill all the minumum system requirements? Because I can't install After Effects CS3 because my CPU won't support SSE2.

I had an earlier version installed a long time ago, if i remember correctly. I don't think there's too many changes. I should be able to run it.

Edit:

Oh, umm.. It seems i still have it installed? How the hell could i miss it.

Ok, then i think i have no problems anymore..
