I just downloaded an update of Limewire Pro and I'm having difficulty installing it. When i try to install it says an older version is already running, but my older version wasn't even opening and i had uninstalled it.
Please help.
Thank You.

Open task manager (ctrl/alt/del) & see if there's a LW process running. If there is, end the process.

How did you uninstall LW? Uninstalling via Add/Remove Programs can cause problems, with remnants of LW left behind. If you uninstalled that way, use your computer's search to look for all files & folders with limewire in the name & delete what you find.

Restart your computer & now install LW.

The right way to uninstall is start > all programs > limewire > use the uninstaller there.
