If you get MSI errors, try the international installer

I aslo had this problem. There is an installer cleanup utility that worked for me. Run the utility, then install again. Here's the link to get the utility.

that worked for me

This link with the Windows Installer Cleanup Utility works wonders. Thanks.
This was exactly my problem: I keep getting these 2 error messages when I try to install either the limewire update or an all new limewire -
error 1714 (The older version cannot be removed. Consult your technical support group.)
error-1603 fatal error during installation. Consult windows installer help (Msi.chm) or MSDN for more info.

The cleanup thing dont work, neither does deleting all reg keys of LimeWire. And its not so easy having to download over 14MB to get the international installer on dialup.

After you downloaded the clean sweep, did you open it and find limewire in the list, and click on limewire and then click on remove?
I then restarted my pc and was able to download the newest version of limewire.

Thanks, This worked for me 2

I have been using a computer for about six months and i can not firgure out how to install limewire . Right now i go to winmx and do not have a problem please help. so i can enjoy limewire. i have been trying for more then two days, thank you

This worked like a charm. I was unable to remove the program using Start->CP->Add/Remove Programs, so I deleted it and then ran a registry cleaner--still no dice. I sent tech support a note, but who knows when that will get some love. This was great, and it fixed my problem completely. The upgraded version is humming away and I am very happy--you rock!
