When I was installing the Pro upgrade, there showed a message “dllhost.exe - Application error. A Breakpoint has been reached . (0x80000003) occurred in the application at location 0x77b4367f.” I could not shut the dialogue box. When I ignored the message and tried to run Avast, another box popped out, “C:\program files\AVAST software\avast\avastUi.exe. one ore more arguments are invalid.”
I’ve tried reboot several times, uninstalled it in safemode, and re-installed it in normal mode. But the same messages kept popping out.
Anyone could help? Thank you!
