How did you uninstall LW? If you did it via Add/Remove programs (or the Vista equivalent) that's the wrong way & can cause problems. Open Task Manager & check whether there's a LW process running...if there is, end the process.

Try reinstalling now. If it still doesn't work, use your computer's search to look for all files & folders with LW in the name & delete what you find. If you've changed LW's saved folder from the default location, & are saving files to a folder with limewire in the name...careful that you don't delete that saved folder & lose your downloads!

Restart your computer & see whether LW will install now.

Did you try all the fixes below?
