Windows installer doesn't exist? Windows 7

[hshirely]

When I try to install a .msi file, it just... doesn't happen. I just, can't. It asks me what program I would like to use to open this/search the web for suggested programs.
Nothing.

This may help. I've never tried it, so use at your own risk.
