Last post by XMan2015 - June 23, 2026, 02:48:09 PMJust to give an update on this in case some are interested. As of today, Microsoft has NOT fixed the issue, in 24H2 or even in 25H2. I have 3 tickets opens for more than a year with Microsoft and they are still open with 0 comments from Micro$oft.
Thank you

Last post by Administrator - November 15, 2025, 04:03:44 PMHello Terry,
by googling around it seems that mms is effectively disrupted in some way in version 24H2:
https://learn.microsoft.com/en-us/answers/questions/3882324/mms-steam-protocol-does-not-work-in-windows-media
and the suggestion to fix the issue was to rollback to version 23H2; please, note that version 25H2 is already available so you may eventually try to upgrade to the latest Win 11 version.
Hope this helps
Kind regards

User interface components / Re: Ctl3d.BoxedBinary
Last post by Administrator - June 12, 2025, 12:30:11 AMCould you be so kind to report me the exact version of the Btn3Dmms64.dll installed on your PC? Please, verify also if you have some other instance of the DLL installed somewhere else because it's likely that there could be a versioning issue of a newer version of Ctl3dMagic.dll referencing an outdated version of Btn3Dmms64.dll

User interface components / Ctl3d.BoxedBinary
Last post by tdellapenna - June 11, 2025, 05:02:18 PMGetting a system.invalidcastexception when using the new dll. Below is the additional information. Any ideas on how to fix this problem. It looks like a problem from 2.0 to 4.0
Additional information: [A]Ctl3d.BoxedBinary cannot be cast to Ctl3d.BoxedBinary. Type A originates from 'Ctl3dMagic, Version=2.0.0.0, Culture=neutral, PublicKeyToken=fed1aeb89f8dba89' in the context 'Default' at location 'C:\WINDOWS\assembly\GAC_MSIL\Ctl3dMagic\2.0.0.0__fed1aeb89f8dba89\Ctl3dMagic.dll'.

Last post by Administrator - March 27, 2025, 04:38:39 PMHello,
Windows updates are sometime buggy themselves and this seems to be one of these cases; probably something was deleted inside the registry because, being DirectX stuffs implemented through COM classes, it's likely that the CLSID identifying the class of the effect was removed in error: let's hope that this will be fixed soon by Microsoft.
Kind regards

Last post by XMan2015 - March 26, 2025, 07:14:21 PMI was just going to write about this. 
Yes that is exactly the problem, the I3DL2REVERB effect is failing with a REGDB_E_CLASSNOTREG (class not registered) error.
So it is a bug introduced in the Windows 11 24H2 build 26100.3476.
A previous Windows 11 24H2 build 26100.2605 does not have that issue. Just like any other 23H2, 22H2 builds.
I already open a ticket at Microsoft regarding this. I added this information today.
Thank you
