There could be a few reasons why this is the case. Since the WebViewer is an ActiveX control, Windows tries to block its installation. Most of the time this is a good thing because ActiveX controls can often be used to compromise a computer. However, in this case, we want to allow it.
Here are a few steps that need to be taken to force Windows to allow the installation of our WebViewer.
1. Begin by clicking the Start button.
2. Type UAC into the text field and press enter.
3. The User Account Control dialog window will show the current settings.
4. Lower the slide bar down to Never notify and click OK (you will be prompted for a reboot).
5. After rebooting the computer, do not launch Internet Explorer from a Quick launch shortcut in the Start menu. Instead, click on All Programs.
6. Look for the link to Internet Explorer (not the 64-bit version).
7. Right-click this link and choose "Run as administrator".
In most cases, these steps will allow the WebViewer to load. However, there are certain Antivirus programs that will still try to block the installation. Contact the Antivirus software maker for instructions for allowing ActiveX controls to load.
After attempting to install the Webviewer, Windows may still block the installation because it can't verify the publisher. If this is the case, you will see this popup:
