How to Enable JIT Debugging in Windows XP

By Dave Wilson

JIT (Just In Time) debugging errors in Microsoft Windows XP can appear when an Internet Explorer add-on program or script fails to run properly while browsing the Internet. JIT debugging error output is used by software developers to pinpoint the root cause of program failures to resolve program errors. Enable JIT debugging in Windows XP through the Control Panel when Web programs or Internet Explorer lock up or crash without displaying error-notification information.

Step 1

Close all open Internet Explorer windows by clicking the "X" in the upper right corner of all "Windows Internet Explorer" windows. Click "Start" and then click "Control Panel."

Step 2

Double-click on the "Internet Options" applet in the "Control Panel" window that appears.

Step 3

Click the "Advanced" tab in the "Internet Properties" window that displays.

Step 4

Click to clear the "Disable script debugging (Internet Explorer)" check box and the "Disable script debugging (Other)" check box.

Step 5

Click the "Apply" button and then click the "OK" button to save the setting.
