The new au 2.0 msi file is included as part of the base kernel exe file, which adds around 300KB to it.

we should investigate and move it into a kernel bundles instead to reduce initial download size.

it should probably be in the same place as where we put jusched.exe and jucheck.exe.

Once the au2.0 msi is downloaded, it should be invoked right the way to install the au 2.0.
