An .MST file is a configuration file that is used in customizing the parameters while the software applications are installed on the Windows OS. Generally, the MST file is used in the software testing and development environment for configuring the test versions. The MST file can be used to customize the components, features, setup properties while installing the software application. Both the MST and MSI (Microsoft Windows Installer Packages) files can be edited using the Microsoft Orca Editor program.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the MST extension without any issue. However, if you still have problems with this, you may use the option of MST file conversion to a different format.
We hope we helped you solve the problem with the MST file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the MST file (apart from the lack of the proper application installed).
First - the MST file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the MST file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the MST file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the MST file has not been completed and it cannot be opened properly).
If you have additional information about the MST file, we will be grateful if you share it with our users. To do this, use the form here and send us your information on MST file.
