Origin will not download Battlefield DLC's Error: Certificates do not match! Dev: Cert check failed! Check Origin Build.
As the title says, Origin will not download my DLC's I just bought. It keeps throwing the "Dev: Cert check failed!" even if I keep pressing OK button. I tried to google this but I didn't get anything...
I contacted the support and they told me to stop all processes until I had Windows related stuff left, then I had to remove all temp files in Windows folder and from another place (Windows Button + R --> type in %temp% and hit enter and delete all of the files)
This worked for me so if you have the same problem you might want to try that.
For me it simply helped to start Origin as the administrator. hope it will help you too 🙂
