Not a huge deal, but on wine, running 'ppviewer.exe /q' installs powerpoint
silently. Awesome.

So I wrote an ahk script for it, since it's one of the few 'Wine Supported
Applications'. Ran the test script on windows, but it hangs, since at the end
of the install, this message box pops up:
Microsoft Office PowerPoint Viewer 2003 Setup completed successfully.

On wine, of course, we get nothing.
