Question / Help Error: Could not find any D3DCompiler libraries

[ciphernemo]

Wow, I haven't run into any apps in a long time that gave an error on the first launch. How amateur is this open source app?

Received this error on the first launch: "Could not find any D3DCompiler libraries".

• Windows 7 Pro 64-bit SP-1
• Downloaded latest OBS Studio from obsproject.com as of this post.
• No mention of this error in a quick scan of your wiki.
• Opted for default install options: only browser plugin selected
• Log file from %APPDATA%\obs-studio\logs...

A search on the forum, looks like this may solve it: https://obsproject.com/forum/threads/could-not-find-any-d3dcompiler-libraries-0-13-2-browser.44314/

Installing that DirectX SDK resolved the issue. For Windows binaries of OBS Studio, why is this not bundled with the installer, or at least linked or suggested instead of just getting an error?

The installer does prompt you to install them if they are missing. However the installer is 32 bit so only checks for the presence of the 32 bit DLL. Some other app on your system misbehaved and installed only the 32 bit DLL globally.

Good to know, thanks!

On an unrelated note, love app's granular customization so far, with controlling every aspect of the capture. A little clunky to learn without any guidance, but reasonable after half an hour of playing around with it. From transforming capture area to changing video size. Works great!
