Error message OxC0070643 Description event exec_finished

Hello Christine,
We apologize for the inconvenience caused. We request you to remove conflicting antivirus products if any (http://avgread.me/1K1IqEh) and then remove AVG traces using remover tool( http://aa-download.avg.com/filedir/util/AVG_Remover.exe ). Please restart to complete the uninstalling process. After restarting your computer, you may need to manually uninstall/delete any remaining AVG applications from 'Control panel' and also 'search' for a folder "AVG Remover"(usually in 'C' drive) and please delete it manually. And then I request you to install AVG Antivirus Free by clicking on http://files-download.avg.com/inst/mp/AVG_Antivirus_Free_692.exe .Thank you.

I am trying to install AVG free, but it gets to 97% download and it stops and shows the above error message. 

I am running windows 8

Can anyone help with this issue?

Thanks, Christine
