My Avast Pro 10-U license expire on April 27, today I renew it, it gave me the latest Avast Premium multi-devices V20.
I try activate the new subscription on my existing computer with the new activation code, but no luck it would not take it as valid code???
So I uninstall the old Avast, login to my account, download the new Avast Premium Security for Windows. 383MB exe file.
Try install it, but it never finish properly. It always end itself with no error. No icon on desktop.
Tried uninstall, reboot, then start the new install three times. No help.
Later on I found that the AvastUI.exe never exist. The Avast services will not auto starts.
I remember years ago, there was some fool-proofed UNINSTALL program somewhere that will remove prior installation clean, would that help and where to get it now?
Would someone direct me how to solve this problem?
Thank You, Phi
