Can't choose "update my existing prestashop"

[tomokaikuji]

Hello

 

I would like to update my prestashop from 1.4.7.0 to 1.4.8.2.

 

I followed the updating prestashop guide and when I launch the update script, it doesn't let me choose the radio button

"I want to Update my existing Prestashop to a newer version (currently installed version detected: v1.4.8.2)"

 

It is defaultly selected to "I want to install a new online shop with Prestashop.

 

 

Please could anyone help!!

Did you ever get an answer to this? I'm having a similar problem, and would love to find a way to actually get past it with a manual upgrade (or anything else).
