There was a product key when I first got it but I recently had a new hard drive installed and they didn't put a product key on it. I'm guessing that the repair shop called Acer and ordeed a new hard drive (laptop still under warrently) and they jut sent a new hard drive.
I almost had luck installing WMP 11. It told me I had to download .NET Framework and .NET Framework SP1 (weird, I have Windows SP2). I download that then download WMP 11 in the middle of installing it says someting like the install was not sucessful, and something else but too tired to remember. It automatically goes to system restore and starts back up again. I still didn't have any luck. I had just installed a bunch of Microsoft updates and stuff. I dunno why WMP 11 is so ard to get. I had no problem installing it before. New hard drive takes some time gettng used to.
Is it even an Acer hard drive? My old hard drive had the Acer logo blow the computer picture screen when you press the windows key + Pause/Break button, this ard drive dosen't show any logo there. And the Acer toolbar for Windows is gone. I tried downloding it but have sme trouble downloading it. Maks me wonder if Acer gave me re-used hard drive or smething. If they take old hard drive and r build them or something.
