Error message 1

Error message 2
Error - 1628: failed to complete installation
This error occurs when the InstallShield application is corrupted or is damaged.
I have Windows 7. I keep getting Error 1607: Unable to installShield Scripting Runtime when i try and install the game Command and Counquer Generals. Please help.
