Interrupt custom action

[d-v]

I've got a custom bootstrapper executing an msi package with several custom actions that take around 5 minutes. It's currently possible to cancel in between the custom actions and pressing cancel does usually kick in after a while but sometimes it seems to get stuck. Is there any way to signal from the bootstrapper to the install engine that I want to cancel the execution of the currently running custom action?

Yes. The custom actions need to send progress so they can be interrupted. Note, this is how custom actions can be canceled even if the package wasn't included in a bundle.

The code for the WixQuietExec custom action exists here: https://github.com/wixtoolset/wix3/blob/develop/src/ext/ca/wixca/dll/qtexecca.cpp

can WixCA be used in wix v4?
When I try to use it, i get this error.
error WIX0094: The identifier 'Binary:WixCA' could not be found. Ensure you have typed the reference correctly and t hat all the necessary inputs are provided to the linker.
I've read that it needs WixUtilExtension.dll. Can I reference that with nuget?
I found this on nuget registry
<PackageReference Include="WixToolset.Util.wixext" Version="4.0.2" />
but the nupkg actually has "WixToolset.Util.wixext.dll".
Are they the same thing?

Never mind, it looks like I just needed to use Wix4UtilCA_$(sys.BUILDARCHSHORT) instead

I am having a similar issue. I wanted to know how exactly do I send progress from custom actions? Where do I send it? I am fairly new to Wix and Custom actions. Thanks.
