Hi Sue,
Please take a look at this article (http://avgclick.me/W10compatibility). It could be a compatibility issue with Windows 10 depending on what version you are trying to install.
Every time I try to install AVG I get the message that the install has failed, Error code 0xC0070643, Description eventexec_finished. I have used the AVG removal tool and re-downloaded using the 64bit download link provided in other posts in this forum. I'm trying to install on a brand new Dell laptop running Windows 10 Any help would be appreciated
Thank you for your response. The article gives no help, it doesn't mention anything about the error code I am getting. After following the instructions I am given the option of installing AVG Security Suite which asks for a license number, which I don't have as this is a fresh install on a new computer.
