To Perform a Manual Installation

  1. Download all relevant Viz Mosart Installation Files to the preferred location. The default location is C:\Mosart\Installers. You are advised to make a sub-directory for the installers for a particular version/build containing all the MSI installer-files and any other supplemental files. This directory should be named using the Release.Version.Patch.Build naming convention, for example: C:\Mosart\Installers\ for Viz Mosart 3.4.5 build 12345.

  2. If you are upgrading from an earlier Viz Mosart version it is recommended to take a backup of your current installation settings before you start the installation of the new version. See Viz Mosart Backup below.

  3. Double-click an MSI installation file, and follow the prompts to complete installation.

  4. Repeat the above step for all relevant installation files.

  5. You need to start a set of Windows services to make Viz Mosart run properly. These are automatically started when the computer is started.

    1. The safest is to reboot the computer to verify that the automatic start of the services is working.

    2. Service names will be displayed as in the screenshot below:


Version Numbering

Installation folders are named with the Viz Mosart version number. All files inside that folder also have the corresponding version number attached to the filename.

Version numbers have the following syntax:

  • Major.Minor.Revision.Build (for example


  • Major.Minor.Revision denotes the Viz Mosart Version Number

  • Build denotes a patch number

Example: Installers\\VizMosartServer-

In this example, the computer has a folder for the Viz Mosart release, containing associated installers.
Every significant code change of Viz Mosart results in a change to the Viz Mosart version number. This increases either the major, minor, or revision number.

Patches are identified by having a higher build number than the remainder of the files.
