Create a Transform (MST) file

This article describes how to prepare Transform (MST) file for Windows installer.

What is a Transform?

A Transform (*.MST) file allows you to collect installation options for programs that use the Microsoft Windows Installer in a file. They can be used on the Installer (MSIEXEC.EXE) command line, or used in a software installation Group Policy in a Microsoft Active Directory domain.

Use Orca utility to prepare a packaged installation of MiaRec screen recording client. You can download Orca as a part of Windows SDK or from our website

What is Orca?

Orca.exe is a database table editor from Microsoft for creating and editing Windows Installer packages and merge modules. The tool provides a graphical interface for validation, highlighting the particular entries where validation errors or warnings occur. More details can be found on Microsoft web-site.

Open MiaRecScreenRecorderSetup.msi in Orca utility (request this file using a download form if you don't have it yet).
