When trying to install either the Chinese, or Japanese Language Kit version 1.0 the following error appears:
"The installer cannot update the version of Performa system software on the disk '/'. Please read the file 'Read Me' on the disk 'Install 1' for more information."
To properly install the Chinese or Japanese Language Kits (CLK or JLK), remove the Launcher from the System Folder or use the Extension Manager to deselect the Launcher. After restarting, the installer should work properly.
