Informix Ultimate-C and SQW

According to several sources, one of them being at http://www.ibm.com/developerworks/data/library/techarticle/dm-0801doe/ it seems that SQW (SQL Warehousing) feature set should be included with Informix Ultimate-C Edition 10.50.xC7 for Windows and Mac OS X. I thought that might be very good news, however... I've installed Ultimate-C Edition on 32-bit Windows and haven't seen SQW components, like Design Studio, DWE Console etc. Can someone help explaining if SQW is really available and if it is, how to get it for use with Informix Ultimate-C? TIA, Darko Krstic
