Can't install Elements 9

When I click on any of the exe files in the installation folder (after unzipping), I immediately get a message “Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item”. Then Norton pops up a message “Setup.exe is not safe and has been removed”.

I have now got around this problem.

  1. I disabled my Norton Security - That on its own made no difference.

  2. I disabled Windows 7 User Access Control - The issues remained.

  3. I right clicked on the Cubase Elements “Setup.exe”, selected Properties, Selected Security. “Full Control” was not ticked, so I edited it to Allow it (screenshot attached).

When I then ran the Setup.exe is ran without any issues.
