Upgrading video driver for nVidia ION2 adapter in Acer Revo RL100 downloaded directly from nvidia website surprisingly leads to the installer failing with "This graphics driver could not find compatible graphics hardware" error. Funny, right? Turns out that video adapter can only be upgraded by the driver update downloaded from Acer website. However, driver provided by Acer is quite old compared to the latest version sourced from nvidia directly, and we all love to always have the latest and greatest drivers installed, right?
