avast older version and AIS license question

Quick questions here.

a) Can I use an Avast Internet Security license for Avast Pro?

b) Where can I download older avast versions? Need download link for

-- avast internet security 5.0.677
-- avast Pro 5.0.677

Friend wants to downgrade to version 5.0.677 and had deleted his older file installer. I have the free version but needs in (b).

Thanks

but i wouldnt downgrade.

 

I am using Avast Internet Security with the free License received.
I think you can use Avast IS Licence for Avast Pro. But you can always install the Internet Security & customise it.
The latest version of Avast seems better - so what is the use of the older version?

 

Thanks for the replies.

@Brocke,

Just checked the links you gave and I found out that it was for the free version. My friend was looking for the AIS and avastPro verson as stated in (b). Any links available?

@century,

About the AIS license using it in Pro, I/we were having problems earlier with avast not accepting the license of AIS. Well, after 2 uninstalls/installs I let him be and went home..
Will visit him tomorrow.

My pal was having BSOD which I also saw in the avastForums (in Windows 7 x64) and it was a suggestion there to downgrade from 5.1.889 to x.x.667...just trying to help him out

Any links for (b)?

Thanks all

 

I don't have links for .667 but if you find them and use the AIS installer, you can do a custom install without the firewall and anti-spam and then you'll have practically the same as Pro version but the license still works
