Installer begins properly and downloads the Exp\ Elite.msi file.

The installer continues to download an isscript.msi file and opens a window
displaying "1621: failed to verify signature of file isscript.msi".

The installer then quits.

(just to reiterate, this is on a clean WINEPREFIX using wine version 1.1.7)
