Solutions to “Unlock Failed”: Cannot add new emulator instances in NoxPlayer Multi-Drive

Hi dear users! If you’ve encountered this error message: “Unlock Failed” when you are trying to add new instances in Multi-Drive, you could resolve this manually before it’s fixed in our future update.

(this is a known bug for some PC types that we’ve scheduled to fix, sorry for the trouble that Nox caused you).



Follow the instructions below:

Step 1: Close NoxPlayer.

Step 2: right-click the icon of NoxPlayer on your desktop and open file location, you’ll be directed to the bin folder

Step 3: download this fixed exe file (which we’ve uploaded to Google Drive), paste it to the bin folder to replace the original file (also named “NoxPack”) with the new one.

Step 4: Launch NoxPlayer again and try adding new instances in Multi-Drive! 🙂
