avast program version 2014.9.2011 won't update to 2014.9.2013

[MrToad]

avast program version 2014.9.2011 won't update to 2014.9.2013 on win7Pro 64bit. Main screen says update...I click to get to the update screen , click the update button repeatedly...nothing happens. I just updated a nearly identical win7Pro 64bit PC with no problems...same firewall. I ran into a similar problem with  2014.9.2011 not updating on an XP PC...installed the new version over top...what a nightmare...had to uninstall completely install the new version then re-register. I'm not going down that road again
Any suggestions?

Do you (or did you) have any other anti-malware software installed?
If so, which one(s) ?

If not:
1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition.
Here are the installer links. Note: You need to be ONLINE during this install.

Avastclear : http://files.avast.com/iavs9x/avastclear.exe
Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

2. Uninstall Avast by control panel  [If you don't have Avast in control Panel go to #4]
3. Uninstall in Safe Mode using Avastclear.

4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn't) - reboot.

5. Be Sure Too Check Once Uninstall is Complete:Device Manager>View>Show Hidden Devices
If there is anything related to Avast with a yellow triangle then uninstall it (highlight, right click) and reboot.
6. Install the version you downloaded.
7. Reboot.

Also, here is the download links to the offline installers but in some cases the offline installer doesn't work, whereas the online one does.
It has something to do with the wrong SFX in some installers......I've read several posts on issue with VISTA with the offline.

Why?    Eddy just did give the proper instructions. 

And we are also a few versions beyond this outdated topic so the bug my not be relevant anymore either.
