Here’s the mail I got recently

• What is the version of internet explorer you are using?

• Any recent changes done on the computer?

A runtime error is a software or hardware problem that prevents a program from working correctly. Runtime errors might cause you to lose information in the file you're working on, cause errors in the file (corrupt the file) so you can't work with it, or prevent you from using a feature. Unlike stop errors, runtime errors don't typically cause Windows or a program to stop working.

What is a runtime error?

I would suggest that you run the Fix it tool available in the below Microsoft kb article and check if it works.

Fix Runtime Errors in Internet Explorer

If the above step fails then I would suggest that you check if any add on is causing the error in the internet explorer I would suggest you to try opening Internet explorer in the no add-ons mode.

Click the Start button, click All Programs, click Accessories, click System Tools, and then click Internet Explorer (No Add-ons)
