ProgressBar - Python and Powershell

[Alec Taylor]

Why are you writing an installer in Python and Powershell?

Just write an installer in WiX, NSIS or Inno like the rest of the sane world.

Alternatively take a look at MakeMSI or the script python uses to
generate there .MSI.

Anything else is WAY too non-standard to consider.
