Frequently Asked Questions

What is aja.dll?

Metadata analysis shows aja.dll is a Dynamic Link Library (DLL) developed by OBS Project for OBS Studio and is described as “OBS AJA Windows module” .

DLL files (Dynamic Link Libraries) are shared core modules used by Windows programs to run efficiently without duplicating code. Most errors occur because the DLL is missing, corrupted, or outdated. In many cases, reinstalling the related application, repairing Windows, or replacing the DLL resolves the issue.

How do I fix missing DLL errors?
1

Fully uninstall and reinstall the program causing the error. If you are not sure what program is broken, look at the available file metadata above for hints. If a clean reinstall fails, download and install the DLL file manually.

Install the .DLL

Move the extracted DLL file into the root folder of the software that is giving you the error (where its .exe file is located), or place it in the system directory below:

32-bit → C:\Windows\SysWOW64
64-bit → C:\Windows\System32
3

Restart the Program

Close and reopen the program or game so Windows can look for and load the new DLL file.
