AACLK (Apple Asia version of the Chinese Language Kit) is not a standalone product and not available in the U.S. It is only for purchasers of the localized Chinese system software who want to be able to use the other Chinese (traditional or simplified) at the same time. (Like Chinese language kit, the localized Mac OS is available for Traditional and Simplified Chinese.)
AACLK is not intended for use outside of Chinese countries and hasn't been tested with non-Chinese systems. The AACLK installer will not behave correctly in some scenarios, such as when other LKs are present, on other localized systems, etc. AACLK and CLK are made by cooperating teams at Apple, but for different purposes. In time, they may be combined.
The only way a U.S. customer can get AACLK is to buy the localized Chinese system from a dealer of localized systems and applications, but the cost of the localized system package is much higher than the cost of the U.S. CLK. Like the localized Chinese Mac OS, AACLK is not supported in the U.S.
In terms of CLK 1.0 or 1.1 working with System 7.5.x or 7.6.x, please use the following steps for installation:
Installation1. Install the WorldScript Updater 1.1 (or select the International Option under Custom Install for System 7.6).
