Setting PDF-XChange Editor as the default application for viewing documents in Internet Explorer is a two-step process. The first step is to adjust the File Association preferences:

1. On the File tab, click Preferences. The Preferences dialog box will open.

2. Click File Associations in the Categories menu:

3. Change the setting for View PDF files in Internet Explorer and Register NP-Plugin for other browsers from Do Not Change to Yes. This makes PDF-XChange Editor the default PDF program for Windows.

**NOTE: After clicking Apply, the value will change back to Do not Change, this is intended and simply means that further consecutive presses will not attempt to make changes to this value again. This helps to prevent users from receiving repeated UAC prompts.

The second step is to adjust the Internet Options for Internet Explorer:

1. Move to the Control Panel of the local computer.

2. Click Internet Options. The Internet Properties dialog box will open. Click the Security tab and ensure that the Enable Protected Mode box is not selected, as detailed below. This disables protected mode in Internet Explorer, which is necessary in order to run the PDF XChange applications.

3. If the box is selected then clear it and click Apply. If you are running Internet Explorer 11 then a warning will appear that states: "The current security settings will put your computer at risk." This is an automatic system response - your computer is not at any risk. Click OK.

Please note that if you do not have the most recent version of Internet Explorer installed on your computer, then it is highly recommended that you update your version and restart your computer as soon as possible.

If you want to make PDF-XChange applications the default PDF programs for other browsers then please see KB#303.
