OK thanks, I think I'm getting there <smile> So, I have my MsiPackage for my download...
<MsiPackage SourceFile="..\SharedComponents\bin\Release\SharedComponents.msi" InstallCondition="(ProductAInstalled) OR (ProductBInstalled)" DownloadUrl="https://mycompany.com/downloads/blahblah/sharedcomponents.msi" DisplayName="Shared Components" Compressed="no" Vital="yes"> </MsiPackage> One piece of missing info I cannot find in the documentation, is where to define the credentials in order to be able to download the file - as it's a secure download requiring a username & password. As far as I can see, a nested <MsiProperty> element is used to pass properties *to* an MSI, not properties used to *download* the msi in the first place. Indeed if I add my credentials <MsiProperty Name="userName" Value="myUsername"/> <MsiProperty Name="password" Value="myPassword"/> burn pops up a dialog requesting the credentials - which in its self is great, but not what I want it to do. Where in this element can I store my username and password required to download the msi package?
