Are you running it as administrator, and using the correct version? There's a new and old version depending on which ICS you have installed.
That mount line refers to it being mountable as write, not that it needs it.

Okay. Sorry for the delay in response, but I've been having a heck of a time getting this to work. I did run the bat file as admin and I got this fail notice:

Frustrated I put my head to the grindstone, got to work and have succeeded. The A100 running ICS 4.0.3 is now officially rooted. :good:
Here's how I got it to work. I did everything you told me Pio and had no success. I then read the whole damn thread and got really frustrated as none of the solutions were working for me.
I should make note that I am using Windows 8.
One thing sticking out was when I went to uninstall the drivers in the Device Manager
the tablet was showing in 2 places. One was Other Mobile and it had the yellow sign with exclamation mark. This showed the tablet as an A500 no matter how many times I uninstalled it. The other was showing the A100 correctly under Portable Devices.
To make a long story short I went to the A500, right clicked, chose Properties, Driver, Update Driver, chose to pick my driver from the list and it had two choices. Since my .cmd box errors always stated the adb wasn't going through I grabbed sack and chose the Acer Composite ADB interface driver and voila it took!
I then went back to the A10x_A5xx root and double clicked
the run-it win batch file. I double clicked because someone in the thread said that was the only way he could get it to work and at this point what did I have to lose? Well, it ran perfect, the tablet rebooted, I ran SuperUser (success), then Titanium Backup root (success), then Rom Toolbox Lite (success).
I would like to thank you for your assistance Pio. For those struggling with the issues I had hopefully my explanation is clear enough to assist you in overcoming it quickly.
