Windows 8 upgrade Iconia Tab W500

Hi I have been trying to upgrade my Iconia Tab W500 to windows 8 for the past week.  I purchased Windows 8 Pro OEM 32 bit. I can get windows to install without any issues.  I tried just installing windows 8 with the disk (that didn't work I can even get through the setup screen).  So I had to install from windows 7 to windows 8.  I tried both options Keep all settings and files and the clean install.  I also tried the Acer upgrade assistant.

 

The problem is I cannot get the touch screen to work.

I've tried installing the touch screen drivers, device control drivers, AMD display drivers, and updated the bios.  The only time I got it to work temporarily in 8 was after installing the Touchscreen firmware (1007.2005) after doing that it worked immediatly after the install.  It prompted me for a reboot and after the reboot it wouldnt work any more and I can no longer reinstall the firmware since it is now up to date.

 

I like the performance a lot better in windows 8 (windows 7 has problems even streaming video from amazon and netflix just a little delay between audio and video)

 

However without touch ability the W500 is a poor laptop...   Has anyone else sucessfully upgraded can you point me to the correct driver to get it working.

    Hi, I'm also planning to upgrade my Tab to Win8. May I know during your process of installation, did u delete all the partition or just some partition had been deleted?

    Sorry for the late reply.  I have done both methods,  I tried the inplace install and the clean install.  *You can install in a typical way ie you cannot boot from the windows 8 media, you have to run it in Windows 7.  I also tried the acer upgrade tool located here http://us.acer.com/ac/en/US/content/manually-upgrade however I was still unable to get my tablet to work with the touchscreen.

    Thie issue is due to OEM version of windows 8 requiring windows 8 ceritified hardware, to disable this problem in windows 8 try the following:
     
    Windows Key + X, choose Command Prompt (admin).  Then type the following two lines:
     
    bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
    bcdedit -set TESTSIGNING ON
     
    That should get you past the signing issue.
     
    This fixed the issue for me but left a watermark in the lower desktop saying TEST MODE,
    fixing that is a different google search.
