Create and edit an MST file

ImportantThe following article uses options that are available starting with the Architect edition and project type.

This tutorial will guide you step by step through the creation and editing of a simple transform file for 7-zip File Manager It is addressed to those who have no previous experience in using the Advanced Installer to create and edit MST files.

For example let's say you need to install 7-zip File Manager with a desktop shortcut. Since this is not included in the package the only way to install it for all the machines on which you will deploy the package is to create a transform, starting from the original MSI.

NoteA transform file is a set of installation data which can be added or replaced into a setup package only at install time. It can be applied to an MSI installation package by setting from command line the TRANSFORMS property.

1. Create transform

If Advanced Installer is not currently running, start it by double-clicking on the desktop icon or by selecting it from the “Start > All Programs > Advanced Installer” menu. When the application starts, you will be presented a dialog where you can choose the type of the project you want to create.

Start Page

  • Select the “New Transform” template from “Transform” project type.
  • Press the [ Create Project ] button.
  • Select the 7-zip File Manager MSI file you just downloaded.

The MSI is now loaded and you can start making the changes that you want to be saved in the MST file

2. Add the shortcut

Files and FoldersSwitch to the “Files and Folders” page by selecting it in the left-side panel, then select “Desktop” folder from the list of predefined ones.

In Desktop folder you can add the new shortcut to 7-zip File Manager. Right click in the right-side pane after you selected “Desktop” folder and select “New Shortcut To -> Installed File” from the context menu. From the “Select Installed File” dialog browse to Program Files 64\7-Zip folder and select the file “7zFM.exe”. In the newly appeared dialog choose a name for your shortcut - like in the following screen-shot. Press the [ OK ] button and the shortcut will appear listed in the “Desktop” folder.

3. Save the transform

Now that you have added the shortcut to your project let's save the MST file.

Save Project Click on the [ Save ] toolbar button and a “Build Project” dialog will appear showing you the build evolution. It is a build operation even if you pressed “Save”, because the way of a transform file is created.

Run Project Once the save is complete, click on the [ Run ] toolbar button. You will see the installation wizard running normally, but with the transform applied, so you should get the shortcut installed on your Desktop.

Congratulations! You have created your first Advanced Installer MST file. You can find the MST file next to the MSI, if you have not changed the output path.

4. Edit existing transform

To edit a transform file just double click on it and Advanced Installer will launch. First it will ask for the MSI on which the transform applies, this is the only way to load it, please select the original MSI of “7-Zip File Manager”. You cannot load and edit the transform if you do not have the original MSI on which it applies to.

In this example we will add a new registry value under HKCU hive, called “Version”, to store the version of the installed product, by going to Registry page, under HKEY_CURRENT_USER\Software\7-Zip. As you can see in the image below.

Now you can save and run the MSI with the new transform applied as you did at step 3 from above.
