Unable to install Avast due network error.(Win7 Prox32)

I've downloaded the newest installation package several times and changed even between Home and Pro packages. Error stays the same, and as far as I've found out it's due to a network error. Has anyone else experienced the problem?

Here is the error log that Avast installer gives:

Was your version of Avast a fresh copy or an old one

I mean if one doesn't work delete the file do a restart then download it again
clear your temp files too

I have had a problem at time only getting a part of a file & this was a fix
so your first download may had been a bad one then each copy from then on was a copy of the corrupt file
Just an idea
& there doesn't seem to be any difference between Home & Pro

I first thought it would have been corrupt, but that was not the case. I downloaded it again and no result.

Now the problem is solved folks. Guess what! Windows installed some updates and voila, installing works!

Thanks for the help.
