Why does the MATLAB 7.9 (R2009b) installer display the splash screen but fail to launch?

When I run the R2009b installer, the splash screen is displayed for a short period of time, then it disappears and nothing happens. The setup.exe process is still running, but nothing comes up.

This bug has been fixed in Release 2010b (R2010b). For previous product releases, read below for any possible workarounds:

This issue can indicate a conflict with VPN software. As a workaround, close any currently running VPN software and run the installer again.

If you are seeing similar behavior when launching MATLAB, see the bug report here:
