This is a registry error related to Internet Explorer program. You do have 2 options in order to overcome the error message. Please follow the below instructions to fix the error.
1. You can simply turn off the error reporting from your browser which will stop error pop-ups.
* Open the Internet Explorer browser from your computer.
* From the top of the browser window click on "tools" and go to "internet options" from the menu.
* Click on "settings" through the "advanced settings" tab.
* From the settings find the two options related to "disable script debugging" and mark both check boxes and disable the feature. Also uncheck the box which says "display notification about every script error". Then apply the settings to the browser and press "ok". Now you'll never receive any error reports regarding Internet Explorer.
2. You'll have to re-install the Internet Explorer application as your second option if the above setup doesn't work on you. If you still receive error messages with the browser after disabling the above feature that means you'll have to re-install the complete program due to corrupted registry entries.
That’s a very unusual error for Microsoft Internet Explorer 8 and I haven’t encountered that one yet. Since you’re on Microsoft Windows XP, it ships with Microsoft Internet Explorer 7 by default. Since that error is very unusual and seems to just appear after you upgraded to Microsoft Internet Explorer 8, try uninstalling Microsoft Internet Explorer 8 to downgrade the browser back to version 7.
Visit Download Revo Uninstaller then download and install the free version. Once installed, run Revo Uninstaller then select Microsoft Internet Explorer 8 from the list then click “Uninstall”. Follow the instructions to completely remove everything the program created on your computer. Once version 8 is removed, click “Start”, “Control Panel”, “Add or Remove Programs”, and then click “Add/Remove Windows Components” on the left pane.
In the “Windows Components Wizard” window, scroll down and uncheck “Internet Explorer” then click “Next” and then “Finish”. Restart your computer.
After booting, repeat the steps to go back to the “Add/Remove Windows Components”. Check “Internet Explorer” to activate the browser then click “Next” and then “Finish”. After this, upgrade it to Microsoft Internet Explorer 8 again. You can download a compatible version from FileHippo: Microsoft Internet Explorer 8 for XP.
