This often occurs if either the Activation doesn't work correctly, or it didn't install correctly.

Reinstall it and select Repair when given the option to Repair or Remove.

For Vista/Win7/Win8/Win8.1 make sure you right click on the installer and select Run as administrator from the list.

You might also need to turn you Anti-Virus software off, or simply disable the shields while you install it.
