Install Invalid Signature

This topic is basically for the Prizm Viewer control and is not recommended.

I have met the System Requirements needed for my PC and Checked my Internet Explorer settings and Prizm Viewer still does not work. What should I try now?

Try the following:

Change your Run or Install Invalid Signature settings.

•	Open an Internet Explorer browser window

•	Open the "Tools" menu

•	Click on the menu item titled "Internet Options"

•	Click the "Advanced" tab

•	Look for the heading, "Security"

•	Check the box labeled, "Allow software to run or install even if the signature is invalid"

•	Click the OK button

•	Test Prizm Viewer.

•	Uncheck the box labeled, "Allow software to run or install even if the signature is invalid" after viewer has been installed successfully.
