Streamlabs OBS and Streamlabs Chatbot require some additional files to be installed on your system before using the software, or you may run into issues. Please download and install both the 32- and the 64-bit version of the Microsoft Visual C++ 2017 Redistributable. After installing reboot your computer.
If you get a setup failed error, please go to windows apps and find the newest c++ entries (usually bottom of the list) and click on each one. Choose to modify then repair and restart after repairing both of them
