I'm running SBS 2011. Using the .98 version of the tool I am able to install and get SuperFetch working great. The newer tools 1.0.1 and 1.0.2 fail with a exitCode 1. My guess is that the newer versions are doing some checking that the older version does not.
%SystemRoot% points to C:/Windows so that part I know is correct. I also noticed the RAR correctly uncompresses into the correct directories but then looking at "inst.cmd" under #10 I see some instructions/tests after the unrar command that I don't really understand prior to importing the registry keys. Should I just manully excute the reg file and see what happens? All works great when I use the old .98 tool but neither of the new tools work.
I'll install SBS 2011 and see if I can reproduce the errors.
The difference between 0.81 and newer versions is that 1.0.1 and 1.0.2 can be run from DVD and Network drives.
But the exit code is no good.
I'll be back on this.
