I recently had trouble playing Netflix in Chrome; it was giving me an error (M7357-1003) that said I needed to update my WidevineCdm component. I tried this, and it didn’t work. I tried a bunch of other fixes I found online and none of them worked.
The real fix is simple. So simple you will smack yourself if you’ve been trying to fix this.
Run Chrome as an administrator. It’ll work now. 🙂
