This is a selfextracting file. Just execute the file and under device manager select display adapter then press the update and have disk. This says it is only for the Acer Extensa but I needed the driver for a Compaq 1255 presario notebook. (I found that they share the same video card)I thought I would never find it. Compaq sucks!!! Of course on their site you can find no reference to the driver, go figure.
