Hi everyone. 
  
here is a problem that has been bugging me for some weeks now. 
  
I work for a non profitable organization and at the moment we don't have a corporate solution for file anti-virus/protection. 
  
so what I have done is I have deployed Microsoft Security essentials with the "setup.exe /s /runwgacheck" command line in program options and it worked fine. 
  
Now my problem has to do with updating the clients with daily updates. What I have done is the following: 
  
- Created a package 
- Created the program 
- Created advertisement with the setting "Always rerun program" 
  
So when I download a new version of the essentials update I update the DP with the new file, change the mandatory assignments date and then re-run advertisement. 
  
The thing is that the program is being advertised to clients but the new source file is not downloaded to the clients. instead of that I receive the following error: 
  
 
  
Is there something that I have been missing? Maybe a setting that will force the source file to be re-downloaded its time I rerun the advertisement? Or, can I Achieve what I want to do in some other way? 
  
I know that if I create a new advertisement my problem will be solved but until the next update when i will, again, have to create a new advertisement. 
  
Thank you in advance
