Try copying the contents of the disc to a folder on your desktop.
Then disable any AntiVirus or Firewall programs (anything unnecessary).
You could also try temporarily turning off UAC (User Account Control). To do this, open the Control Panel, then type 'UAC' in the search box.
You should see a link called 'Turn User Account Control (UAC) on or off'. Select it, then uncheck the box, select 'Ok' and reboot your computer.

Then go back to the files you copied to the desktop and try and find a Setup.exe or Install.exe and run that.

To turn UAC back on, just follow the same procedure but make sure the box is checked at the end.
