Setting Transform Details
The Transform Details dialog, which you see when saving a transform file, contains
options that flag error conditions of a transform. You set the error conditions to ignore.
It also contains validation options. Normally, if the error conditions exist, errors are
generated when the transform is applied to the standard installation.
In most cases, if you create the transform using Wise for Windows Installer, you can
leave the defaults on the Transform Details dialog. See
MsiCreateTransformSummaryInfo in the Windows Installer SDK Help.
! Base database
This is the .MSI on which this transform is based. Do not change this. If this
transform is applied to a database other than the one specified here, an error is
generated during installation.
! Suppress Transform Application Errors
The following checkboxes let you suppress certain errors if the transform attempts to
perform certain operations on the base database. In most cases, you can leave the
default settings in this section.
• Add existing row
Suppress errors from occurring if the transform attempts to add a row that
already exists in the base .MSI.
• Delete missing row
Suppress errors from occurring if the transform attempts to remove a row that
doesn’t exist in the base .MSI.
