Internet Explorer Security Settings for MapGuide

Overview

Adding our site to Internet Explorer's list of Trusted sites and lowering security settings for our site has been found to fix these MapGuide problems:

• Internet Explorer 9 or 10 default settings may block installation of the MapGuide Viewer.

• A few users have reported problems printing from MapGuide with Internet Explorer 8. See Problem Printing from MapGuide with Internet Explorer 8 for more. (No users have reported printing problems with Internet Explorer 9 or 10 yet, but it could have the same printing problem and solution as Internet Explorer 8.)

We don't recommend changing Internet Explorer security settings unless you are having one of the above problems.

Adjusting Internet Explorer security settings for MapGuide

Ensure that you have ADMINISTRATOR RIGHTS on your computer to complete these steps.

The term ADMINISTRATOR RIGHTS refers to your computer's settings that allow you to install software and do other system things on your PC. If you have problems installing or if you don't have ADMINISTRATOR RIGHTS rights on your PC, contact your system administrator or support person. If you are using your home PC or a PC that you maintain, then you probably have the needed ADMINISTRATOR RIGHTS.

Open the Internet Explorer Tools menu Security tab as follows:

1. Pick Internet Explorer's Tools menu
2. Pick Internet Options to open the Internet Options dialog box.
3. Pick the Security tab.

In the Security tab:
