Trying to reinstall firefox on a windows 7 machine and I get "The application was unable to start correctly (0xc0000142)"

In troubleshooting a different issue I uninstalled Firefox. After fixing the other issue I'm tying to re-install Firefox and am getting an error message that says "The application was unable to start correctly (0xc0000142). Click OK to close the application." The title bar of the window says "setup-stub.exe - Application Error." My PC is a Dell Studio 19 All-in-one running Windows 7 Home Premium.

When I look up that error on Microsoft's forums, I find suggestions ranging from an incompatible update/hotfix to malware...
