The Fragment element contains an unhandled extension element 'util:RegistrySearch'

Question

Learning how to create Wix Booloader so that I can install .NET framework with my msi install package. Anyway I am stuck with an error for an unhandled extension element. Code is below

<?xml version="1.0" encoding="utf-8"?>
<!--

Can anyone please explain what my error is I have included the correct namespace and I can't see a reason for the error!

When you compile your code with candle, do you `-ext WixUtilExtension`? — Yan Sklyarenko, Mar 13 '14 at 13:59
ok I have changed the -ext WixBalExtension to WixUtilExtension but now I have error with default bootstrapper application Unresolved reference to symbol 'WixBootstrapperApplication:WixStandardBootstrapperApplication.RtfLicense' — codem, Mar 14 '14 at 14:08
You should not replace, but add another extension. Like this: `-ext WixUtilExtension,WixBalExtension`. I might be mistaken with syntax, though - just play with it until it works — Yan Sklyarenko, Mar 14 '14 at 14:11
thanks heaps its done now, I was trying a few combinations to get multiple extensions to work. It turns out that it needs to be "-ext WixBalExtension -ext WixUtilExtension" I gave up before as I was unsure that I was able to use multiple extensions. — codem, Mar 14 '14 at 14:17

The WiX extension for the namespace xmlns:util="http://schemas.microsoft.com/wix/UtilExtension is provided by a dll named WixUtilExtension (this assuming you are using Visual Studio). Right-click on the References node in your project and add a reference to the WixUtilExtension dll.

Thanks. I'll add you may be able to get these dll's from nuget as well. This helps on my build machine where I haven't installed Wix (as I did locally) – granadaCoder Feb 01 '17 at 18:57

also if you are running on the commandline, you need to add `-ext WiXNetFxExtension` to your `light` call and maybe the `candle` call, too. https://wixtoolset.org/documentation/manual/v3/howtos/general/extension_usage_introduction.html – phyatt Aug 28 '19 at 16:34
I meant `-ext WixUtilExtension`. – phyatt Aug 28 '19 at 16:52
