GS/OS 5.0: King‘s Quest Compatibility

I have an Apple IIGS, and I would like to use King's Quest (from Sierra ON-LINE). Running under System 5.0 with only the icons of 5.0 and AppleWorks GS installed, I tried to install King's Quest and its icons, but the computer always hangs and I have to restart.

Without the Icons, the system performs OK. The same setup with all Icons worked fine on version 4.0 of the operating system. Can you explain?
There are a couple of things to watch when using some of the King's Quest programs:

1) If your version of King's Quest includes the program and icons, eliminate all of the King's Quest icons from your hard disk -- except for the program icon. Deleting these icons will not effect the functionality or performance of the program; these icons were used by the programmer when writing the program, and were not removed before the program disk was duplicated for distribution.

2) When using GS/OS 5.0, you must have 768K or more of memory (minimum used to be 512K). Alternatively, run the program from its program disk (which contains an older, less memory consuming version of the OS).

Good Luck King Graham, Gwydion, and Rosella!
