I keep getting the error message that the "setup files are corrupted"; when running the setup file for v4.3. This happens whether I save the file first or run from the web. I did uninstall v4.2 first as recommended. No problems with v4.2. I tried running the files "as administrator" to no avail: I am running Vista HP fully updated. Used the coral networking choice to download; the file was not available on the geek site. Apart from this file, my computer is performing perfectly. Any comments?
