The custom actions used in the WixSQLExtension do not have the
"no-impersonate" bit set, so they never run as LocalSystem (except in the
rare instance that the installation were being performed by a service
running as LocalSystem). Thus, if you are using the WiX-supplied SQL support
you must launch the installation itself from an account with the desired
access.
The only ways to run a custom action as LocalSystem are to run it deferred
with the Impersonate attribute set to "no" in the CustomAction element in
your authoring where the Execute attribute is set to some in-script type
("deferred", "rollback", or "commit"), which cannot be run from the UI since
they must be between InstallInitialize and InstallFinalize in the
InstallExecuteSequence table.

Subject: [WiX-users] Using Integrated security for connectionstring in
CustomAction
Hello all!
Let's say that i am using a C# custom action, to validate the database
connectionstring that a user has entered in a dialog.
If the user has selected to use Integrated Security, and the account of
the Windows Service that will be running the application is "Local
System",
that would mean that when the service is running, when connecting to the
database it would use the "Local System" to try and access it(which is
what i want).
In my c# custom action, when i try and connect to the db using Integrated
Security, would it use the "local system" account to connect(which i think
is the account the installer is running as)? or will it use the account of
the user that is logged in the machine(which will fail to connect)?
In the latter case, any ideas on how to make it run as local system?
Thanks in advance,
Stelios
