When I try to load Internet Explorer I receive the error "Explorer has caused an error in mfc42.dll". The OS is WIN ME, Internet Explorer is version 5.5. I have tried: install latest roxio/adaptec patches, system restore, extract mfc42.dll, etc. to no avail. Please help.

First do this; Run a find files for mfc42.dll and list here what shows up....You should have the file as an application extension .dll in your C:\WINDOWS\SYSTEM (folder). See if the file is 973KB or 917KB (ck. the C:\Windows\System folder). I wouldtry to replace it w/ the 973KB file that should be on your ME CD via System File Checker (SFC). Any chance there is a ZIP Drive on the system? This file is also used as a common file for Iomega applications, and as an audio driver (aureal), and as an add on (pws), also could be more, just looking @ my 98SE OS. I will check my ME Box when others are awake to see what I come up w/ on a find files there.

But first try to close all open programs EXCEPT Explorer then try to start IE...If it starts OK, Close it then open 1 of your normal start programs, repeat the test of IE...keep this up opening all programs listed in your start menu in msconfig until you get a hang or the same error mssg. You really might also try updating to IE 6.0 it works fine w/ ME. Have you tried repairing IE 5.5 via Add/Remove Programs and clicking Remove then Repair IE? Are there any browser add-on's or extra toolbars (nastyware) attached to IE that you know of?

After you list the files yu find list them here & I'll try to help, I'll be backkk!

Got it..Any chance you have Direct CD installed? Here's a link to MS KB for the problem resolution;
http://support.microsoft.com/?kbid=227176
(remove any clear spaces)

From what I gathered quickly you must re-install Direct CD (your cdrw writing software), check like I said earlier by closing the Direct CD program and see if IE opens correctly then.

Good Luck. I'll also post the link & found to deal w/ other mfc42.dll errors.

OK, I checked my ME Box which has Direct CD on it also. You shouldn't have that mfc42.dll in anything actually connected w/ Direct CD..If you do, you need to delete that .dll from the folder. It only needs to actually be in the C:\WINDOWS\SYSTEM folder as it will get called out for a multitude of items including Explorer or IE. Like I said before it should be 973KB in size...If it is 917KB then it has been changed & needs to be extracted from the ME Disk & replaced in the C:\Windows\System folder.

Thanks for all your help brother. I tried everything you said to no avail. I tried extracting the mfc42.dll and other dependent dll's - tried registering them, etc. I ended up clean installing. Again thanks for your time I appreciate.

Your problem may be due to a spyware or hijacker, specifically ?Xupiter? (or ?Xjupiter)?.

I have Windows 98SE and a CD-ROM (no CD-RW). But I got exactly the same error whenever I opened the Internet Explorer.

As it turned out, this was caused by ?Xupiter? (or ?Xjupiter?). After I cleaned it, the error message was gone.
If your webpage starts with Xupiter.com, or Xupiter runs at Windows Startup (check Startup by running msconfig), you got it.

To remove it, do the following

1). Download Spybot Search and Destroy and run it. http://beam.to/spybotsd, or
2). Download Ad-Aware and run it: http://www.lavasoftusa.com
3). If the above does not work, remove it manually by using registry editor (regedit)

Editing the registry is risky, so be sure you have a verified backup before saving any changes.

Start | Run and type regedit
Edit | Find and type Xupiter in the box. Delete every Key, Value, and Data. Hit F3 key to find the next.

If any of the above steps is not clear,use the comment box and request for further information.
