How to Update MERLIC

To update your MERLIC version, you have to use the MVTec Software Manager (SOM) for the installation. However, you can first check if a new MERLIC version is available in the MERLIC Creator as described below.

Checking for Available Updates

Per default, MERLIC shows a dialog upon startup that notifies the user when a new update is available. If an update is available, the notification dialog will remind you of the update upon every startup until you have updated your MERLIC version.

In case you have disabled the notification dialog, you can check in the MERLIC Creator if a new MERLIC version is available: open the "Help" menu entry and click on "Check for Updates...".

Updating to a New Major or Minor Version

To update your MERLIC version to a new major or minor release, e.g., 5.2.0 to 5.3.0, you have to use the MVTec Software Manager (SOM).

The installation process of a major and minor release is the same as for a regular MERLIC installation as described in the topic Installing MERLIC. Thus, the new version will be installed beside the existing MERLIC installation. The MVApp files will be associated automatically to the newly installed MERLIC version. In addition, the Windows start menu entries will also be associated to the new MERLIC version.

If you don't require the previous MERLIC installation anymore, you can uninstall it as described in the topic How to Uninstall MERLIC.

Updating to a New Maintenance Version

To update your MERLIC version to a new maintenance release, e.g., updating MERLIC 5.2.0 to 5.2.1, you also have to use the MVTec Software Manager (SOM).

However, in contrast to updating to a new major or minor version, you do not have to perform a complete new installation. Instead, you can manage your existing installation via SOM as follows to update the existing installation files.

  1. Start SOM via the respective desktop icon or the Windows start menu. If SOM is not installed, use the extracted executable file "som.exe".
  2. Go to the page "INSTALLED" via the menu on top. You will see a list of all installations of MVTec products on your system. If an update to a new maintenance version is available for one of your installed MVTec products, the following icon is displayed on the respective product: 
  3. Click on the menu icon of the respective MERLIC installation and select "Manage Packages".
  4. Select the new MERLIC version from the drop-down menu and click on "APPLY" to start the installation of the new MERLIC version.

SOM also detects MVTec products that have been installed by other means, e.g., a MERLIC 5.0 version that has been installed via the previous offline installer. However, these installations cannot be updated or uninstalled via SOM.
