Question / Help OBS runs in background - Unable to load 'amfrt64.dll', error code 126.

[Beachdancer]

OBSD worked for a day, but now runs without appearing on the screen. Windows 10 may have updated since OBS worked and so may have changed something.

In Task Manager I can see OBS as a background process but not as an App.


On clicking to run the software, a window opens for a moment and dissapears without really opening.

Yesterday it was working, then windows updated.


The log says

"Unable to load 'amfrt64.dll', error code 126." only means your GPU doesn't support the AMD plugins
(because your GPU is Nvidia)

"NVENC supported" means it managed to load the Nvidia plugins, so it's working correctly.

That is NOT the cause of your issue.

Try to run OBS Studio portable mode in different folder: https://obsproject.com/forum/resources/obs-and-obs-studio-portable-mode-on-windows.359/

Thank you for the suggestion. I added the --p and it made no difference.

Please provide a log from that session so that we know that Portable Mode was correctly enabled. Please also upload full uncut log files so that we can see the log from start to finish. You can use the "Upload a File" button below.

Have you checked to see if the OBS tray icon is in your system tray? If it is, can you right-click it and check if the menu says "Hide" or "Show"? Try toggling that a couple of times.

The log says portable m0de false. This is what I ran:

"C:\Program Files (x86)\obs-studio\bin\32bit\obs32.exe" --p





TYrying again with --portable (copied and pasted from the forum page on how to do it.


That produced a different failure... an error window saying failed to create directory- ../../config/obs-studio/basic

It didn't produce a log

I don't know what is a system tray is or where to find it.

The log file in my orginal post is a full uncut one.

Download zip file of the obs studio: https://github.com/jp9000/obs-studio/releases unpack it to the "c:\obs" folder, for example, and make it portable. If you want new icon on the desktop - right click on the obs32.exe or obs64.exe file and choose Send to>Desktop (create shortcut).

 

[RytoEX]

Using "--p" did not work because the command-line option to engage Portable Mode is apparently "--portable" (two hyphens) or "-p" (one hyphen). I am aware that the guide on this says "--p" with two hyphens.

Your OBS Studio installation is in your Program Files folder, which usually requires administrative access to modify/add/remove files or folders in it. Since Portable Mode creates its own configuration directory inside the installation folder, it couldn't do that without administrative access, so that is probably what caused the error you saw. Creating an installation just for Portable Mode is probably easiest here, as @Suslik V suggested.

A system tray is the "tray" of icons usually located next to the system clock in your system taskbar, often called the Start Bar on Windows (the bar that contains the Start Menu).

That log doesn't show the OBS shutdown process, so it's not immediately apparent that it is a full log. It is easier to review logs as attachments or uploads than as embedded in forum posts. Also, forum posts have character limits.
