Question / Help I can't even open OBS

[Rowan]

Whenever I try to run Obs it just says "Failed to initialize video: unspecified error." Please help. What is going on and how can I fix it?

 

[Sapiens]

Could you provide some information about the system you're trying to run it on? Version of Windows? Type of GPU?

I have windows 7
I don't know my GPU
