Hi,   
  
 I just started working on using the Update Deployment Project action. It works fine on a vdproj that generates the installer, but on one that generates merge modules, I get this:   
  
  
 Setting property Product.ProductVersion to 1.2.3.4   
 Error executing Action : Could not update field ‘ProductVersion’ as it could not be found.   
 Source : DeploymentProjectAction   
 StackTrace : at VSoft.MicrosoftDeployment.ProjectFile.UpdateField(String category, String property, String value)   
 at VSoft.MicrosoftDeployment.ProjectAction.(ICustomActionExecuteContext context, ProjectFile project, String property, String category, String field)   
 at VSoft.MicrosoftDeployment.ProjectAction.OnExecute(ICustomActionExecuteContext Context)   
  
 Looking at the structure of the files, it looks like merge modules use Version instead of ProductVersion as well as store that info in a different block.   
  
 Thanks,
