The 176KB version is identical in code to the general release version, but is optimized for loading on Windows 98.
A much larger version, at 225KB, this particular riched32.dll file is intended to cover all localized versions. This is also dependent on the GAPI32.dll file. This particular version was released by the Microsoft Exchange group, and is also the only version that cannot be distributed.
