This really needs to get resolved. I can't use any program on my computer that doesn't have an icon on the desktop and I have a program that I need to use! I have tried the fixes listed and nothing is working. I'm getting ready to pay someone to take me back to Windows 7. I wonder how many people have surrendered and bought an Apple just so they can use their computer.
