I've been trying to update my AVG Free 2015 on Windows 10 but am prevented from doing so by some hidden installation. The message I get when trying to update the AVG is "Update has detected running installation. Complete that installation before starting update".  I am not able to uninstall the program to reinstall due to the same problem.issue.  Is this a fault with the windows 10 package I recieved or is there something I've missed?
