OBS Studio requires updated Microsoft Visual C++ 2022 Redistributables. Please run both of these installers in order to continue:

Visual C++ 2022 Redistributable [64 bit] - vc_redist.x64.exe

Visual C++ 2022 Redistributable [32 bit] - vc_redist.x86.exe

Both the 32 bit and 64 bit versions need to be installed, even if you have a 64 bit version of Windows.
