Unable to use util in wix3

[qrnch-jan]

Hello,

I'm trying to register an event source from an installer, but I get the error:

error CNDL0200 : The Component element contains an unhandled extension element 'util:EventSource'.  Please ensure that the extension for elements in the 'http://schemas.microsoft.com/wix/UtilExtension' namespace has been provided.

What I have done:

• The .wsx file contains, on the Wix tag, xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"
• The light.exe command line has the arguments -ext WixUtilExtension
• The tag is referenced as <util:EventSource>

What I've tried:

• I tried to use another util component (ServiceConfig), but I get the same error (well .. but for util:ServiceConfig), so I get the distinct feeling that this problem is confined to util. (I am able to use UI extensions (with the appropriate -ext)).
• I've cut'n'paste from examples which I presume work, and I get the same problem -- making me think there's something wrong with my installation. (The WixUtilExtension.dll is in the bin directory).

I'm using version 3.11.2 on Windows 11.

Living by the mantra "How hard can it be?" I chose to ignore all the "Don't try to register/deregister your service manually from within the installer" warnings I stumbled on and had the installer run the service executable (because it can register the service and register the event source) as a custom action. I believe I aged roughly three years during the two days I was working on this. (Learned a lot though, but the most important lesson was to heed warnings about trying to avoid using built-in installer features).

Did you include the -ext switch to candle.exe? CNDL0200 is a compiler (candle.exe) error.

Sigh.. I can't believe I didn't notice that. Another lesson learned: It's not always a good idea to stick things in a script. I would have caught this if I had run candle manually.

Thank you!
