Post Installation
To avoid some software crashes and other issues, the Windows system should be configured to be compatible with visionCATS.
Graphics performance preference
As current Windows versions are unable to choose the most powerful graphic adapter for visionCATS, a manual preference should be added.
Warning
Without this preference, visionCATS may crash when Windows is switching of graphic adapters.
Note
On low end system, only one graphic adapter is available, and the preference is not needed.
Open Graphics settings
In Desktop app mode, click on Browse button
Go to the visionCATS installation folder, select Platypus.exe and click on Add button
Open the Options for visionCATS entry
In the Graphics preference, select the High performance (system which may experience issue will have a different card under Power saving than under High performance. If the card is the same, the settings will not change anything). Click on Save after selection, and then restart the visionCATS client
Important
The preference should be added for each Windows user using visionCATS on each client machine.

Inform users to close visionCATS before locking the session
It is possible to have several users on the same Windows machine, and to switch between them. However, if a user locks its session, the visionCATS client will still be running, and the next user will not be able to start visionCATS.

For several technical reasons, it is not possible to have several visionCATS clients running on the same Windows machine. Therefore, it is important to close visionCATS before locking the session.
Important
If several users are using the same Windows machine, they should close visionCATS before locking their session.
