Gentlemen, I’m totally confused by this thread. http://download.windowsupdate.com/msdownlo...en/rootsupd.exe (dated Monday, January 15, 2007 15:38:48) will NOT work on Windows 98, as mentioned by erpdude8 in post #1. It displays a message stating this, and instructs the user to update his/her operating system. Microsoft has verified that they will NOT be updating Windows 98 root certificates in future as “support” for that product has ended. http://www.download.windowsupdate.com/msdo...658a4f6d589.exe, referenced by the_guy in Post #3, is dated Thursday, September 07, 2006 14:11:31. Although it does not display any error messages when run under Windows 98, it doesn’t display any message indicating it has successfully installed (or done anything). Nor does running it solve the root certificates problem for Windows 98. http://www.download.windowsupdate.com/msdo...f144720f759.exe, referenced by the_guy in Post #3, is dated Thursday, December 14, 2006 15:43:04.

In post #6, MDGx provides the following link for “Microsoft Internet Explorer 5.xx/6.xx Root Certificates Update (RCU) for Windows 98/NT4 SP6a/2000/ME/XP/2003/Vista (English): http://download.windowsupdate.com/msdownlo...rtf/en/4702.htm However this is simply a link to a description of an update, not a downloadable file! In post #6, MDGx also provides the following link: Unofficial RCU for Windows 98/NT4 SP6a/2000/ME [235 KB]: http://www.mdgx.com/files/RTCERTUP.EXE. However, this link returns and “Not Found” error (404). In post #9, MDGx states: Official RCU found on WU [Windows Update] works with all 98/98SE/ME/NT4/2000 [and all newer] OSes. Therefore unofficial RTCERTUP.EXE is not needed anymore, and references the following two links: http://download.windowsupdate.com/msdownlo...rtf/en/4702.htm, which is a description of the update, not a downloadable file, and http://download.windowsupdate.com/msdownlo...64cff75229e.exe, which is the same do nothing (for Windows 98) update mentioned above. Thus, none of these downloads provides a solution to the Windows 98 root certificates problem that has existed for several months.
