Hello, I have Windows 7 64-bit system on a Dell Inspiron N5050 PC, with an Intel Core i3-2370M processor, 2.40 GHZ CPU, and 6 GB RAM. Today I attempted to install a program on my system, and got this error message: "1607: Unable to install InstallShield Scripting runtime". I can't seem to figure out what would cause this, or how to fix it. Any help is greatly appreciated. If it helps, the program I tried to install was "Zoo Tycoon 2: Ultimate Collection." And now I seem to be getting this: "Error 1608: Unable to create InstallDriver instance, return code: -2147319784"
