Internet Explorer Runtime Error!!*

This application has required the runtime to terminate in an unusual way.

Recent calls from clients has triggered in me a sense of deja-vu. There has again been an unusual number of people who were having their IE web browsing session crash, due to a “Runtime Error”.

Error message: Runtime Error!! Program: c:\Program Files\Internet Explorer\iexplorer.exe. This application has required the runtime to terminate in an unusual way.

Tip of the day: You can cure this malfunction by knowing that it is caused by a conflict with a (possibly corrupted) installed Add-on. In each and every of my caller’s instance, it was the Google Toolbar – so that’s the place to start your troubleshooting.
[Note: to be fair to the Google toolbar, the corruption probably occurred during an update, and was caused by these people having the Yahoo! toolbar installed also. One or the other, folks.]

[update: there has now been a few instances of this happening with the Ask toolbar.]

The quick-and-dirty solution is to go into Add/Remove Programs and uninstall/re-install the Google toolbar, but the way to be sure – or, if you’re getting this error and don’t have the Google toolbar – is to disable add ons one at a time until the problem goes away.

1) In IE, click on “Tools”, then select “Manage Add-ons”, and then “Enable or Disable Add-ons”, as shown above.

2) A list of installed Add-ons will appear. Start by looking for “Google Toolbar Helper”. Select it, and then click on the “Disable” button.

3) Close, and restart Internet Explorer, and surf normally for a while. If you no longer get crashes and error messages, you’ve found the culprit. An uninstall/re-install is now in order (if you want to keep the toolbar, that is).
If you continue to get crashes, repeat the Steps and disable one more Add-on.. until you find the right one by process of elimination.

Today’s free download: Avira’s AntiVir continues to grow in popularity, and the latest major release–a exclusive–shows why this free security program is at the top of the charts. A brilliantly customizable one-click threat killer, baked-in anti-spyware and anti-adware to compliment the antivirus engine, the ability to scan “locked” files, a rebuilt heuristics engine, and infection protections for its own source files are what’s new and notable in AntiVir 9.

    • Asha–
      Yes I did know that. I have been watching IE 8’s development with great interest, as it has features I’ve been waiting for.

      But, I have been using it on my Windows 7 beta machine routinely, and I seem to be able to get it to lock up (aka “freeze”) more often than not (often, with only a single tab open).
      ..I am not sure how much of a role Silverlight is playing in that, though.

      Hopefully this new release will not have those issues.
