CS6 Design and Web Premium -> Install Error "You are already running another installer,"

Hi

I have just downloaded CS6 Design and Web Premium and I have been having problems running the Adobe Installer on a Windows 8 HP laptop. The Adobe installer gets 75% way through the setup process and then stops with error message "Installerfailed to initialise".

I have run Adobe Support Advisor and the error message is "cpsid_82829s6: "You are already running another installer," bootstrapper error has occurred."

I have looked at the FAQ's and have done the following

1. I have checked System Resources -> Process and I can't see any other setup programmes running
2. I have run CS5 Cleaner tool and cleared out any older versions of adobe products
3. Rebooted the laptop
4. Tried running the Adobe Installer and the same error messages appear.
5. Submitted/packaged the Adobe Support Adviser - 40-85436-165301042013

I did prevousily have CS6 Cloud Trial running on the Laptop but all of the porgramms have been uninstalled and the CS5 Cleaner Toll appears to have cleared any remaining elements.

I would be grateful for some help and advice in sorting this out.

Kind regards

Steve
