Hi there
It sounds as though you may be confused with the output files created by Captivate.
In most cases folks want a Flash SWF file created. That file is usually loaded via the HTML page that Captivate also creates. It's sort of a house of cards. The HTML page is loaded by the browser and immediately the code looks for the standard.js file. If that file is found, it is loaded and more information is added to the HTML page. If you fail to upload the standard.js file all operation stops and things fall apart. 
Once the HTML page properly loads, it then presents the SWF.
Hopefully you are seeing from this that there is no single file to upload and run. There are a few.
Cheers... Rick
