Windows Installer Problem

[sefarlow]

I am trying to install a program named Fritzing. I keep getting the following error: "The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance." I also get that error trying to install a program called advanced installer.
