Fix OBS Studio DLL Errors and Crashes

OBS Studio users may encounter:

Runtime Errors: - VCRUNTIME140.dll is missing - MSVCP140.dll not found

Plugin Errors: - obs-browser.dll failed to load - obs-websocket.dll error - Third-party plugin DLL crashes

GPU-Related: - nvEncodeAPI64.dll error (NVIDIA NVENC) - amf-core.dll error (AMD AMF) - OpenGL errors

OBS requires Visual C++ 2019 or later:

Step 1: Download and install: - VC++ 2015-2022 x64

Step 2: Restart computer

Step 3: Launch OBS

For 32-bit OBS (rare), also install x86 version.

For plugin and browser DLL issues:

Step 1: Download latest OBS from obsproject.com

Step 2: Choose "Full" installer option

Step 3: During installation, ensure "Browser Source" component is selected

Step 4: Restart and launch OBS

The browser source plugin requires VC++ runtime - if it fails, the VC++ installation might be corrupted.

For nvEncodeAPI64.dll and NVIDIA encoder errors:

Step 1: Update to latest NVIDIA Game Ready Driver

Step 2: In OBS: 1. Go to Settings → Output 2. Change Encoder from "NVIDIA NVENC" to "x264" temporarily

Step 3: Test if OBS works with x264

Step 4: If NVENC is needed: - Ensure your GPU supports NVENC (GTX 600 series or newer) - Try Studio Driver instead of Game Ready Driver

For persistent crashes:

Step 1: Close OBS

Step 2: Navigate to: `` %appdata%\obs-studio ``

Step 3: Rename "global.ini" to "global.ini.backup"

Step 4: Launch OBS (it will create fresh settings)

Full Reset: Rename the entire "obs-studio" folder to reset completely

Third-party plugins can cause DLL crashes:

Step 1: Navigate to OBS plugins folder: `` C:\Program Files\obs-studio\obs-plugins\64bit ``

Step 2: Identify third-party plugins (not obs-*.dll)

Step 3: Move them to a backup folder

Step 4: Launch OBS

Step 5: Re-enable plugins one by one to find the problematic one

Common problematic plugins: - Old StreamFX versions - Incompatible NDI plugins - Outdated scene collection managers
