If you open the CD instead of Running it, you should sees a file like SETUP or INSTALL.
Right click on it ...then Properties...then Compatibility Tab at the top.
Near the bottom, you will see a checkbox for Run As Administrator.....
The actual problem may be Win 8 compatibility, so while you're there, you might as well check the Compatibility Mode checkbox and select Win 7 or earlier from the drop down menu.
If you still have a problem, do this to the .exe file in ProgramFiles or ProgramFiles (x86)...
Since it is already installed, you might try this first...
To just run a program as Administrator, the option will come up when you right click on the file.
