Limewire will not install
 

I've been using limewire for several years now and recently attempted to download the new updated version of limewire 4.16.6. When I run the installation i get this error message: Error opening file for writing: C:/Program Files/Lime Wire/LimeWire.exe. It gives me the option to abort the installation, tretry it, or ignore it and move on. I tried retry but it does nothing, and when I click ignore, the installation completes, but I cannot open limewire afterwords. I have successfully downloaded other .exe files, it is only limewire.exe that will not work. Can anyone figure out what's wrong and help me out?
