Cannot install avg protection 2015

Hi
I cannot install AVG protection onto my laptop. I previously had AVG which has expired. I bought a multi use, multi machine version so that I could protect all my products. I can downlaod it all fine, but when I try to install it fails and I get the below message

Error code: 0xC0070652
Description: Event exec_finished
Any help please it is driving me mad.
Also I have tried uninstalling and it won't let me do that either. It tells me to finish the installation of the product first. I am just going around in circles.
