RealityCapture 1.4.1 does not start

Hello Rorozhy, when you try to run RealityCapture, is the process running in the Task manager? After you removed Epic Games Launcher, were there some remaining for RealityCapture? Were you using it before? For RealityCapture installation have you used the file from the C:\Program Files\Epic Games\RealityCapture folder?

There is RealityCapture in the Task Manager, and it also flashes for a moment and then disappears. It’s the same whether it’s launched from the Epic launcher or by running from C:\Program Files\Epic Games\RealityCapture. It just flashes and disappears.

Do you mean that you are trying to launch it here or have you used the MSI file to install the app?
If you are using the MSI file, is it after you uninstalled RealityCapture by Epic Games Launcher?

I have tried everything. I want to know if there is any way to use the previous version, such as version 1.3.

To run it as 1.3 version you need to have bought ENT license, which is not possible to buy anymore, or PPI license, but it is not possible to buy credits for exports anymore.
Are you able to run RealityCapture on some other machine? Have you had RealityCapture before?
