Anna, suppose someone upgraded from IE6 to IE7 while still in SP2. *Then*
they installed SP3. What would happen to IE if they performed a Repair
Install using a CD with SP2? I wold imagine that simply uninstalling SP3
would work fine, but I do wonder how the above Repair Install scenario
would pan out.
IIRC, I helped out a friend a while back who had this exact situation and
IE became all screwed up as a result of running the Repair Install. It
wasn't a big deal since I had imaged the hard drive beforehand and was
able to restore the image and try another tack.
Daave...
You raise a valid point and I should have been more explicit in my comment
above. The following comments are, of course, based upon my experience.
The scenario you describe, i.e., the user upgrades from IE6 to IE7 while the
XP OS contains SP2, then *later* installs SP3, and still later (for one
reason or another) decides to undertake a Repair install of the OS (possibly
to rectify a corrupted OS) *does* constitute a problem should the user
attempt to undertake the Repair install with an XP OS installation CD
containing SP2.
Under those circumstances the Repair install will fail early in the setup
process because the system is apparently unable to install the required OS
files and will report that failure (on a file-by-file basis) to the point
where there's no choice left for the user but to abort the process.
In the scenario above in order for the Repair install to proceed (using a XP
OS installation CD containing SP2) it would *first* be necessary for the
user to uninstall IE7 before undertaking the Repair install with that XP OS
installation CD containing SP2. Should the ensuing Repair install be
successful (of course it's not always for a variety of reasons other than
the issue under discussion), then IE6 would be installed as a result of the
Repair install.
Nearly needless to say that IE7 uninstalling process would be awkward to
undertake at the least and (in most cases in our experience) virtually
impossible since in the great majority of cases (again, in our experience)
the Repair install of the OS is undertaken when the system is unbootable. So
there's really no practical way to uninstall IE7 given that situation.
On the other hand if the user had installed SP3 *before* upgrading from IE6
to IE7, then there is no problem (along the lines described above) using a
XP OS installation CD containing SP2 to undertake the Repair install.
Assuming no other problems negating a successful Repair install the OS will,
of course, revert to XP-SP2 and include IE6. Obviously the user could then
install SP3 and/or IE7 should he/she wish to do so.
Also, should the user be working with IE6 and have no interest in installing
IE7 then there's no problem with undertaking the Repair install with an XP
OS installation CD containing an earlier SP.
In any event it would seem that when all is said & done, as a practical
matter it would be best (as Jerry has indicated) in virtually every case for
the user to use a "slipstreamed" XP OS installation CD containing SP3.
Since I haven't had any substantive experience with IE8 I haven't commented
on any problems/issues relative to that version as it impacts the issue
under discussion. While I would assume the above scenarios would be roughly
the same as described above I don't know that as a fact. I would be
interested in hearing of the experience of others in this regard.
