We want do distribute a product presentation as a Flash projector file  
(.exe. file) on CD-ROM. When started, this file generates the Windows XP  
Open File Security Warning (“The publisher could not be verified. Are you  
sure you want to run this software?”). We don’t want our customers to be  
exposed to this warning.  
I guess the warning is triggered because our projector file lacks a digital  
signature. Is there a simple way to add such a signature to the file? Or is  
there some other workaround, addressing this problem?
