Resolution:
You have a script where you create an Automation object. Example:

var impAgent = new ActiveXObject("Spotfire.ImportAgent");

When running the code, you get the following error message:

"Automation server can't create object".  

----------------------------------------RESOLUTION----------------------------------------
Assuming that the object exists and is correctly registered, one possible reason for this error could be that your Internet Explorer Security Settings prevent you from creating the object. Make sure that the "Microsoft Internet Explorer Options Settings" requirements listed on the DecisionSite Client system requirements page (http://support.spotfire.com/sr821/all_sr.htm) are met.
