We recommend disabling any antivirus/firewall software before downloading and installing any Focusrite software. It's also good practice to right-click the installer .exe file and select 'Run As Administrator'.

We have come across some anti-cheat software causing issues - if you have any anti-cheat software (e.g. Riot Vanguard or EA Anticheat) running on the computer, please make sure to disable it before downloading and installing any Focusrite software.

If you still have problems after doing so, depending on the error you see, follow the troubleshooting steps below.

'focusritePal64.dll' Install Issue

To resolve this, disable any antivirus active on your computer and run the Focusrite installer again. You can then re-enable your antivirus after successfully installing the Focusrite software.

Windows Cannot Initialize the device driver for this Hardware (Code 37 in Device Manager)

This can occur when antivirus software interrupts the Focusrite driver installation, or if you skip past the previously discussed Microsoft Visual C++ Redistributable problem. To fix this, make sure to disable any antivirus and run the installer again as Administrator (right-click the installer .exe file and select 'Run As Administrator'). If you notice the Redistributable error message appearing, then please complete the steps outlined in the related section of this article.
