Can't Install AVG Protection

I got an error today about being unable to open avg. I uninstalled it with AVG remover and tried to reinstall it. I was using AVG 2015 and tried to download AVG Protection and have been unsuccessful in installing it. I have tried at least 5 times to install it but once it's almost finished it tells me that it wasnt able to install. I keep getting error: "0xC0070643 Event exec_finished". I've already removed it using AVG remover and just want to know how I can instal avg.
