The following changes have been applied to the installer at

Fixed (hopefully) hotstrings for keyboard layouts that use dead characters -- such as acute (´), circumflex (^), and grave (`) -- so that the keyboard will continue to function properly. [thanks /Torben]
Fixed registry loops so that an entire root key can be recursively searched. [thanks sleepyy35]
Changed the Input command's MatchList so that two consecutive commas results in a single literal comma. In this example, a single literal comma is included at the end of word1: "word1,,,word2".
