Hi Joe,
You may not have missed anything. It could be that the download you made was
corrupted in some fashion, in which case you can just delete the one you
have and do it again. It could also be that there is interference from
another application, things like antivirus and antispyware products can
cause this and should be disabled while scanning with the tool.
Please be aware that the Upgrade Advisor is not the end-all to whether or
not you should upgrade. It can only report on the things it knows are an
issue, it is not "smart" enough to decipher potential conflicts that are not
part of its baseline data. If you bought a manufacturered machine (OEM), you
should also check with the manufacturer for upgrade suitability and
availability of drivers. If you built your own (or had it built for you),
then you should check that the components, particularly the motherboard and
video card, are capable.
