I'm using hp compaq presario CQ40 lap top, and my OS is Windows Vista Home Basic. when i down loaded the microsoft Office Home and Student 2010 Trial, i encountered an error during setup, and her what they say! RG3KK-293F8-CH78B-KV4VP-YJTHW The product key you entered cannot be use on this machine. This is the most likely due to previous Office 2010 trials being installed. (System error: -1073422306)

@bysyfixindap: however correct, that answer was pretentious and unhelpful. Some people (like me) are forced to use Office 2010 for student purposes, as it is the only software compatible with programs like SNAP.

One solution is to clean any trace of the previous Office trial out your registry. If you don't want to risk that, then you must unfortunately buy the full version of Office 2010. As you can see, this problem only exists because Microsoft would murder for a few extra nickels and dimes, and they don't like the idea of students getting 2 WHOLE FREE TRIALS, despite the facts that they typically don't have money to spare, and this issue can quickly snowball into something terrible for a student. I know how frustrated you must be.

It's a tough world. Hope this helps.
