Unfortunately, Error Code 7 (Windows) and Error Code -7 (Mac) are generic OS errors that tell you something is wrong (as if you didn't already know, right?).

Here are the most common problem areas. Your sound driver needs update as well as your video driver. Stop the print spooler. Try disabling the printer.

Make sure the mic is turned on whether you use it or not or even if you do not have a mic.
