I downloaded the latest version but found out that the older version can not be uninstalled. Every time I open the Avast software it appear a popup say it's error, with a error code "555". The information is as follows:
Error
Engine error: License has expired or is invalid. Please update to the recent beta version from Avast website.
• Error code: 555
The application shall be terminated.
Then I can not do anything (except checking the software preference) but to terminate it. Could you please tell me how can I uninstall the 35889 version and to install the latest one?
Thanks very much!
