Hello Min Than Aung

1.DataMiner Cube(client) that is installed and running on your system when you connect to a DataMiner Agent (DMA). It matches the version of the DMA server you are connected to.

2.Launcher Version: This refers to the DataMiner Cube Launcher, which is responsible for launching and managing different versions of DataMiner Cube. It ensures you always run a Cube version compatible with the DMA version you are connecting to,or u can do manually download the version and set with desktop dataminer cube

3.

• The Cube Launcher does not affect the DMA server version. The DMA runs independently on the server.
• However, the Cube Launcher can affect the Cube Client version you are using because it manages which version of Cube is launched.

4.

• No, the Cube Launcher does not automatically update when you upgrade the DMA.
• The launcher updates separately and may need to be manually updated if a new version is available. However, the Cube Launcher does automatically download the correct Cube Client version that matches the connected DMA version.

1.  (plus) if you want to see the versions details u can go on profile and about in general  or versions (Cube Desktop)

• if you want to add version manually there is question(my own problem) for upgrade versions or features versions(cuz manually is kind eazier  you can see the problem below)
