Error installing Sage 300 ERP 2014

HI There

Client upgraded from v6.0 to v6.2 and conversion was successful no error messages. On one workstation, am trying to install the latest version but get the error:

"Feature Transfer error. 

Component: SAU Plugins

File: C:\Program Files (x86)\Sage\Advisor\Update\

Error: Cannot create a file when that file already exists."

It is only happening on one workstation other workstations are fine.

Can anyone help with this?
