Cannot get AVG to load

I had AVG on my CPU.  I have windows 10.  The AVG stopped doing updates so I uninstalled and reinstalled with no problem.  It did it a second time.  I tried to uninstall and reinstall but I keep getting 0xC0070643 error.  The install gets to 75% then stops

Hello Andy,
We regret for the inconvenience caused. To fix the issue, we suggest 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 delete any remaining AVG files and also 'search' for a folder "AVG Remover"(usually in 'C' drive) and please delete it manually. And then install your program 'AVG Protection' by following the instructions in http://avgread.me/1FKGRZI .Thank you.
