Yes I'm experiencing exactly the same problem(s).

Before the Error 1603 message, I get a message as follows:

"LimeWire Pro Error
Error 1334. The file 'donotremove.htm' cannot be installed because the file cannot be found in the cabinet file 'Data1.cab'. This could indicate a network error, an error reading the CD-ROM, or a problem with this package."

On clicking OK the Installer window then shows "Rolling back action" before displaying the Error 1603 message window.

I think there may be a problem with the package.
