:L You Cant Upgrade From WIndows 98 To Windows 7 Your Pc is too old and The hardware is Gonna be outta date

The upgrade version is only to upgrade a previous version of MS office. The trial version does not qualify as previous version to be upgraded. You need to purchase the full product rather than the upgrade.

If you know somebody who has MS office 2003 with a valid product key, you could install that version, and then upgrade it with the product that you purchased

You need a Vista premium disk to upgrade to Vista premium.

Just instert the Vista premium disk and start the installation.

If installation does not start, you will need to boot from setup CD, sometimes you have to change the bios boot sequence in bios settings, to start the installation from CD.

Administrative Rights needed for the installation.

Means that you need to log-in as an Administrator or your User Account must have such rights

The point of an upgrade edition of a piece of software is so that you can upgrade your existing software. You need Photoshop 7 or higher to use the upgrade. If you don't have it, you will need to return/refund your purchase of the cs3 upgrade, and get the full version of the software instead.

Your other option is to purchase an earlier version of adobe photoshop, in order to install it so that you can upgrade it. Seems very round-about but I suppose it would work, and I'll bet if you find adobe photoshop 7 somewhere, it'll be awfully cheap ;)
