Vista - IE Script Error

To start at the beginning: I installed an AIO printer, did a print job fine,
did a scan job & sent it in an email fine on 8/25. I have my update mgr. set
to check for updates but ask me which to install & on 8/26 there were 6 or 7
I chose to install. While the installation was in progress, a minor crisis
needing my attention occured elsewhere in my home, when I came back SOMEHOW
that darned IE8 was being installed. I had that before & uninstalled because
it was causing problems with my winmail so I avoid IE8 like the plague every
time it pops up on updates. I keep hiding it. So during the installation I
chose the "cancel" installation option. Since that time my printer won't do
print jobs & I get a message saying: IE Script Error An error has occured in
the script on this page
Line: 1829
Char: 1
Error: unspecified error
Code: 0
URL: res//ieframe.dll/preview.dlg
Do you want to continue running scripts on this page? Options of yes or no
are given.
This message appears whether I'm trying to print an internet page, one of my
files or an email in my winmail. Furthermore, when it's my winmail it tells
me I have to pick a printer 1st & when I hit print the winmail freezes, I
can't close it. I use escape--it's a no go. NOTHING in the winmail functions.
In order to close it I have to use the task manager. I've uninstalled the
printer & re-installed, updated it's drivers and done test pages. Everything
is fine there. Because of the dates on this I MUST believe this is related to
the cancel of the IE8 installation. How can I make things right again? I
would love to have my IE7 working correctly again AND be able to use my
printer. I don't know how to correct the situation. Please advise. Thanking
you in advance. I am tryingtolearn.
