When windows98 starts up,this message appears:
explorer caused an invalid page fault in module explorer.exe at 0177:00403ale
& windowos couldn't continue

I had same problem on two computers---found that aol 5.0. needs to have explorer 5.0. downloaded to work correctly (per aol )--I did this and have not had any more problems---

The solution to my "invalid page fault in module explorer.exe" was not a hard problem to solve IF YOU know what to do, as to begin with the tech had me at command prompt type edit system.ini and rename explorer.exe from within system.ini to progman.exe so I could access my desktop at least, then to use the run command from the file menu and also to rename win.ini to win.abc for what reason I am not sure. Then to use the windows update files from my pc to access the internet and then download the components of IE that I was either missing or were corrupted which saved my bacon and then to rename progman back to explorer and I was back on my desktop as normal and also to rename win.ini back to normal Hope this helps as I almost did the reformat thing before finally a tech talked me through it and everything returned to normal.

Neither respone 1 or 2 helped me.

Restoring the registry from a backup fixed it.

I fixed it by booting to the DOS prompt (F8 key at startup to boot-method menu, then chose "command prompt") then ran scanreg.exe, which is a DOS program that's part of Win98 (and maybe 95?). A menu option offered choices to restore an older copy of the registry. I chose the prior day's registry and it worked like a charm.

Note, I didn't see the computer go down, but was called in to fix it after a user installed an old 16-bit Windows program and the subsequent invalid page fault failure to run Windows. I have no idea what the installer did or tried to do since I arrived after they left for a business trip.

Anyhow, booting to DOS and firing up scanreg.exe is a nice trick to have your bag.

Editing the system.ini in DOS with Edit and changing the shell=Explorer.exe to shell=progman.exe was another nice trick that allowed me to run msconfig, which in turn showed no entries availabe under the STARTUP tab, which prompted me to run scanreg from the dos prompt inorder to restore the registry.
