I have followed all instruction from previous posts, but none work. I already uninstalled other Anti-virus from the past as well as AVG. I restarted my laptop and it has been giving me the same issue for over a month now. It says to contact Customer Support for help and to give the error code 0xC0070643. Description: Event exec_finished. Thank you.
