I've got an Acer Aspire One D270-1492. I was almost suicidal after trying everything here but nothing worked. This finally worked for me.
1) Go to the following link.
http://www.4shared.com/zip/JIZnHKCV/Intel_Graphics_Media_Accelerat.html
If you don't have an account there, you must register, but it's free.
2) After you get set up you can download the file, in zip form. Unzip it.
3) Next, go to your device manager and the 3600 accelerator with the yellow icon (if there's no yellow icon skip this step). Right click it and uninstall whatever may be in there.
4) Restart machine.
5) Go to the Device Manager again and right click the IGMA 3600 icon again. Click Update driver.
6) In the wizard, select the Install From Specific Location option.
7) NEXT window, select Don't Search, I Will Choose the Driver to Install.
8) NEXT window, select Have Disk (you don't need one).
9) Now, in the Install From Disk window, BROWSE to the location of the downloaded file and open the file.
10) Open the resulting file, and here it is . . . . . click on the "iegd" icon and open it. Windows should begin installing it.
