| If you cannot install a program because of an "Unknown
Publisher" or an
"Invalid Digital Signature," it is probably because you
have Service Pack 2 installed for Microsoft Windows XP. There are
a couple ways around this problem. First, you can try saving
the setup file to your desktop or to any folder on your PC, instead of
running the setup directly from the internet. Then you can simply
double-click on the setup file to start the program install. This
will often get around the problem. If this does not work, you
can also try the below steps to work around the problem: 1. Open Internet Options applet in your Control Panel. (You can locate the Control Panel via your Start Menu.) 2. Click on the tab labeled "Advanced" and scroll to the section labeled "Security." 3. Place a check in the box next to "Allow software to run or install even if the signature is invalid" and then click OK. 4. Try your download again. You should now see an option to "run" the file. (Please note - You may need to restart your browser for the change to take effect.) |
