When i click on the installation programme i downloaded from the website it says:
“This setup does no contain all needed components. Please use internet update or full setup programme.”
WHAT DO I DO???
Do you have another language version of avast! installed? If yes, you cannot install new languages this way. To install additional languages, just click on the corresponding option from the language selection dialog.
If you need, you can download the full setup file (more than 20Mb):
http://download1.avast.com/iavs4pro/setupfulpro.exe
Here you will find ‘all’ languages and ‘all’ features of avast!
