i have a mac, os 8.6.
i downloaded the stuffed .bin file, unstuffed it, and when i run the installer, it comes to the half and then tells me the installer file is corrupt and i should contact the product company for a new copy, and the installer quits.
i downloaded it 3 times, the download finished successfully every time, and the same thing happened.

so, who should i contact?

Well, you better contact nobody if the program you downloaded
is copyrighted, take care.
It's like if I steal a car and if it is not working I contact the former owner..

I have a feeling the poster means the LimeWire application installer....

Was it downloaded from LimeWire's site?

you schuldnt use antivirus(norton) put it to off.

Increase the memory in the preferred memory box to 500k, restart your computer, install the program again. It worked for me. I also run on 8.6
