After issuing a warning Friday that Internet Explorer (IE) 5.01 Service Pack 1 (SP1) wasn´t properly tested by Microsoft, I quickly received word from numerous readers that this release breaks the Help system in Office 2000. "Help requires Microsoft Internet Explorer 3.0 or greater," the warning reads. "You can install the latest version of IE from www.Microsoft.com." (Yes, they use that capitalization). And while this problem doesn´t come as any surprise necessarily, it´s still disheartening to realize that this company isn´t doing what it needs to do to ensure that bug fixes don´t introduce bugs of their own. Therefore, it is with some reluctance that I must advise users not to download and install IE 5.01 SP1, despite the fact that this is the only way--at least for now--for Windows 2000 users to upgrade Outlook Express and other non-browser components of IE.

Dillon Sellars (Thanks) send me a fix for this problem:

IE5.01 SP1 sets the IE build # the wrong way.
In the Win2k Release HKLMSoftwareMicrosoftInternet ExplorerBuild is
52920
After IE5.01 SP1 it becomes 5.00.3103.1000 which is probably difficult
to parse if your are expecting 53103.
So, the solution is set HKLMSoftwareMicrosoftInternet ExplorerBuild
to 53103
