Avast Premium Security will not re-install error

I had to uninstall Avast Premium Security while troubleshooting, issue was resolved, but when I went to reinstall Avast, it errors: “b86362a5.exe has stopped working” is the error message that pops up when trying to install, then aborts install and gives the microsoft “looks for problem online” (e.g. useless help).

I saw others with same error problem and their replies were to contact Avast, so… what gives? Why is this not re-installing? I know my machine isn’t suffering any ill affects now, and I turned off Microsoft essentials while trying to reinstall Avast so as to prevent any conflict as well as told it to Run as administrator to install in case it needed admin rights to install.

Error:

Did you do a clean install ?

I was able to fix this using an Avast Uninstall tool (which works in Safe Mode). After running that, rebooting to safe mode (the tool automatically boots to safe mode on your next restart)… letting it clean up its own mess (uninstall/remove all of Avast Premium Security software). Then rebooted back into windows normal desktop… Ran Avast installer again, and it worked perfectly like its supposed too. Problem solved.

You’re welcome. :slight_smile:
