AVG can't update, won't let me uninstall

For the last several days, I have been getting a pop-up that says AVG is unable to update because another installation is ongoing. I have been unable to correct this. When I try to uninstall AVG, it tells me that "Another installation is already in progress. Complete that installation before proceeding with this install."
Severity: Error
Error code: 0xC0070652
Additional message: MSI Engine: Failed to initialize the package.

This is for AVG 2015 Free.​
