Welcome to the world of Computers my friend. If you are new at this ( at least you sound like it ) then you troubles with software are only starting. Software has the tendency of making people wanna take the PC an have it meet up close and personal with a hammer. Probably where the phrase "hit any key" was born. But you gotta take it easy, hammers and PCs are like water and electricity, they don't mix very well.
If you are having dificulties unistalling the software then most likely the installation is the cause of all your headaches. Perhaps you should look into alternatives on how to uninstall the saftware. I believe that CCleaner has a feature to help unistall software. Do some research and figure it out. Once done I suggest you try what WrecklessEric offered as a good guide to installing the software. Anyways, not every software was made to be liked by everyone. There's bound to be someone who wont like it for what ever reason. Just don't claim it to be a "piece or crap" when the problem may not have been the software but maybe the one installing it. Hey, even I get it wrong once in a while.
