I need to install the .Net framework v2 silently with a progress bar. There
seems to be only 2 ways to do it, dead silent (The user is left staring at a
blank screen for 10 minutes) or full UI, where they have to agree to the
license and click next.

I was able to achieve this with both the 1.0 and 1.1 netfx.msi files, but
the msi for .Net 2 gives an error "To install this product please run
Install.exe"

I've tried pretty much all the normal command line options for msi's both
directly and through install.exe but nothing seems to work. All I want to do
is get it to run with /passive or /qb
