I am not sure about WinME but in Win 98 I have IE6
& when I did a repair on it... I went to control panel add/remove programs & found Internet explorer 6. there. I then hilighted it & went to remove & a window came up giving me the option to repair or remove... I chose repair.
You might beable to do that.
also you might be able to find the IE6setup ( installer ) on your sytem where you can run the install again
Go to start/find/files or folders.....
when the find window comes up...
go to the "Look In" line & type My Computer
then in the search line type in ... ie6setup
click Find Now
Hopefully you can get it straightened out this way
