Start at the beginning. 1. Which OSX version are you running?
2. What kind of mac? (G3, G4, G5, MacPro intel, iMac, etc.)
3. What speed processor?

Check the Receipts folder to see if any previous limewire is listed. For an example of what to look for, see http://www.gnutellaforums.com/mac-os...tml#post132073 If you see Install Limewire.pkg listed inside, then delete it, then try installing again.

I get the impression you are trying to install LimeWire on an older OSX version which the present LimeWire versions will not run or install on. Earlier installers: http://www.gnutellaforums.com/mac-os...link-here.html
