TUXUrlHandler.dll cannot be registered during RAS Agent Setup

We get the Error, that the TUXUrlHandler.dll cannot be registered during the RAS Agent Installation on a Windows 11 24H2 System.
HRESULT -1073741819
When we click on ignore, the Setup goeas ahead without any other Problems.
We try to install the PCAgent.

We have this issue already on two tested Systems.
As this is our first Installation in a POC, we need help on this, how to handle this Problem.



Thanks

Hi @BjoernS

TUXUrlHandler.dll handles URL redirection from the server to the client. This allows users to open URLs from server-side applications on the user's default browser at the client side. If this functionality will NOT be used, then ignoring the error should cause no issues.
If on the other hand this feature is desirable, RAS offers a secondary approach which should work fine with Windows 11 24H2 and similar systems. To enable it, switch on "Replace Registered Application" as explained in the RAS documentation here.

As context to your error: The default option for this functionality enabled "Shell execute hooks" to intercept URL requests. This has been deprecated by Microsoft but is still supported, at least up till rather recent OS versions. The RAS installer tries to enable support for this functionality but Microsoft might have finally stopped supporting it on more modern OS versions. Using "Replace Registered Application" should work in a similar way in most cases with the obvious exception that server-side browsers might complain that they are not the default URL/Mail handlers.
