Pro L-2 not working with Pro Tools in Windows 11

I have two licenses for Fabfilter Pro L-2 One is installed on a Windows 10 computer using Pro Tools 2202.9.0 (latest version). The plug-in is the latest, Version 2.11.

The second license for Fabfilter Pro L-2 is installed on a Windows 11 computer using Pro Tools 2202.9.0 (same latest version). The plug-in is the same latest, Version 2.11.

The installation on the Windows 10 computer works fine, but on the Windows 11 computer, the plug-in window appears, but does not show any audio. In addition, if you touch any controls, it locks up Pro Tools. I have submitted a support request to info@fabfilter.com twice, but have not received a response. I have reinstalled both the plug-in and Pro Tools, but the problem still exists. Any suggestions?

Hi James,

I believe I've been in touch over email as well. Avid had some installation issued when upgrading from an older version of Pro tools on W11. Please completely uninstall Pro Tools first before installing the latest Pro Tools version. Please let us know if that resolves it.

Hi Ralph,

Yes, we have corresponded via email since I posted the query here on the forum. As stated in the email I sent this evening, I just installed the October 25 update to Windows 11 and it fixed the problem! The Pro L-2 plug-in now works with Pro Tools Version 2022.10.

Thank you for your assistance.

Regards.
