LightAct's GUI is black upon launching

Most likely reason is that the GPU LightAct is running on is not a suitable one. Please make sure that you are using a discrete Nvidia GPU and that you've set up your laptop as per this tutorial.

LightAct closes upon launch

One possible step would be to go into C:\ProgramData\LightAct\LightAct4 folder and delete these folders:

If you find a console.log file, delete it as well.

If LightAct still doesn't launch correctly, try to:

  1. uninstall LightAct completely, including the Preferences,

  2. install it again.

In every case, please contact us at [email protected] and let us know what you find out.
