I have a CustomAction as part of an MSI.
It MUST run as a domain account that is also a member of the local Administrators account.
It can\'t use the NoImper
requireAdministrator in the manifest should work.
You can also use a bootloader .exe file which can use ShellExecute with "RUNAS" as the verb (you can use 7-zip to create the bootloader, or there are many other ways).
