Beware Windows Update and manufacturers’ drivers! I have uncovered that neither are reliable for making sure you get the latest version drivers for your device, and in fact, for this, the EETI PCAP Multitouch Digitizer 1.2.0.0, I could only even ascertain that it was a valid and available version from a couple of scattered forum threads and obscure driver sites.
Acer’s own website still lists v1.0.0.0 from all the way back in 2009, well before the Iconia w500 was even out of R&D!
Windows update did find a driver, but when “installed” the driver version had not seemed to change. This happened again with a copy of 1.2.0.0 I manually downloaded and attempted to install. “The latest driver for this device is already installed”. Huh. Could have fooled me!
So, long story short, I examined the instruction file for the driver and found it had some bad references, so I fixed them. And now I have made the fixed driver available. To my knowledge, this is just about the only place you can find a working 1.2.0.0 EETI PCAP Multitouch Digitizer driver at this time. It is dated January 2011, and in my experience I have had far fewer system freezes and other bugs experienced since the upgrade.
That said, I make no warranties – install at your own discretion. Let me know if it helps you!
