Fatal Error: "Error reading application id" when launching D5 Render

I am experiencing a critical issue when attempting to launch D5 Render. Upon starting the application, I receive the following error message:​

*Fatal Error: Error reading application id. Please either write it to steam_appid.txt or use the launcher!*​

After this message appears, the application closes immediately.​

I have tried the following steps to resolve the issue:​

  • Ensured that I am launching the application through the official D5 Render Launcher.
  • Reinstalled D5 Render using the latest version available from your official website.
  • Ran the application as an administrator.

Despite these efforts, the issue persists.

I would appreciate any guidance or assistance you can provide to help resolve this issue.​

Thank you for your support.

Hi @amoudi.93

I apologize for the inconvenience. I have shared this issue further to our team, since this particular error prompt is quite uncommon and is somehow related to the Steam Application or perhaps from a game that you have installed.

Before sending your logs, please check the following:

  • Did you put D5 Render in Steam?
  • Please check if you have installed cracked games (UE-based), we recommend uninstalling them.

Can you generate a log file for us?

Indeed! I deleted a game that was linked to Steam, and D5 started working normally.
It seems there was a conflict with some files!
Thank you very much for your response; I had been struggling with this issue for quite a while.
