What are Secure Transforms

Secure transforms are simply transforms that are kept in a place where the user does not have write access. This might be the root of the location where an administrative installation of the package has been performed (Secure-at-Source transforms). It might also be a share or full path elsewhere on the network (Secure-Full-Path transforms).


You can indicate that the Installer should use secure transforms by special
characters in the TRANSFORMS property (discussed in the next section) or by setting the TransformsSecure or TransformsAtSource properties within the Installer database to 1.


When the Installer uses a secure transform, it will cache a copy of that transform locally. If the local copy becomes lost or damaged, it will restore it only from the original location.
