Avast Won't Update - Avast Anti Virus version --> 7.0.14.73

Dear Support,
I have facing problem about avast cannot manually updated.
i get the virus definition from http://www.avast.com/download-update
after that i just download (avast! 5 & 6 & 7 series VPS update) download and save it into harddisk. the files size for vpsupd.exe is 77.5MB.
when download finished i try double click the files, after that will come out a problem

is there any error message?
did you uninstall your old antivirus before installing avast?
do you have a firewall?

Pondus
