Avast Home Edition Install unsuccessful on Laptop running Win Vista please advise

I am hoping someone can help me out here -Like many others I decided to finally take jump to Avast from AVG 8.5 Free

I am Running Win Vis Home Premium 32 bit on Toshiba Satelite Pro A300 109 Capacity 160 GB - Free 27 GB , " GB RAM

I Read LOTS of posts by various peeps in many forums , How to do this, FAQs , Troubleshooting , etc and felt I was ready

Downloaded – Avast Home from -

Rebooted

Went offline

In order to avoid potential problems of AVG files getting in the way I followed guidelines to use Appremove to remove ALL of AVG Free files easily ( this went smoothly no issues/errors raised )

Rebooted

Tried to install Avast ( r clicked on icon and Run as Administrator)

Avast seemed to install fine – but then msg popped up saying could not complete install

So closed Avast box

In order to get back online to seek support - Had to reinstall AVG Free –

Went back online and searched so far unsuccesfully for answer to install problem

Anyone have any ideas - Huh

I look forward to your replies thanks in advance
