Sawtooth Software: The Survey Software of Choice

SSI Web reports "Run time error 429: ActiveX component can't create object" when trying to calculate utilities for an ACA study.

Version:  Any
Products:  ACA/Web


When clicking on the "Calculate Utilities..." menu option on the "Analysis" menu in SSI Web, the following error appears:

Run-time error '429':
ActiveX component can't create object


This error usually occurs when the CoUtlOLS.dll file (which installs with SSI Web) is not registered in the windows registry, is not present, or has become corrupt.  Sometimes other Windows files that CoUtlOLS.dll file depends on could cause this error to occur.


Sawtooth Software has created a file that will try to register the CoUtlOLS.dll.  It can be downloaded here.  After downloading the file, unzip it and then double-click it.  (This method will only work if SSI Web was installed to the default directory.)

If this does not solve the problem, please contact technical support for additional help.

Demonstrate CBC Using Only Basic Math

This survey will illustrate how Choice-Based Conjoint surveys work. It involves choosing food for dinner at a baseball game. You will take a quick 9-question CBC questionnaire, and then, using simple addition arithmetic, we will analyze your results and place the results into a "what-if" market simulator to see how your results stack up against others who have completed this survey.
