"failed due to bad configuration"

I have a .air program running on nearly 400 pc's in the field.  I have an upgrade I would like to release silently.    I can get the new .air file to the machines automatically.  I would like to run a batch file that will install it, and hit the "Replace" button when it notices that a older version is already out there. 

So, I included the Adobe Air Application Installer.exe in the download, I created a batch file that does this: 

"Adobe AIR Application Installer.exe" -silent -eulaAccepted -desktopShortcut "C:\Program Files (x86)\MascoVSC\vscassets\program\VSC.air" 

THis runs perfectly when the old version is not on the machine, but if it is, I get the error:  "failed due to bad configuration".  

Any help would be greatly appriciated.
