<![CDATA[Qt 6.12 WebAssembly won't install]]>I'm on Windows using the Qt Maintenance tool, trying to install the Webassembly files for Qt 6.12. When i check the webassembly box it shows as 0 bytes and nothing is installed. Is it just me? Is there a command line workaround for installing this on windows?

Run "Update components" before "Add or remove components" to fix the "Add or remove..." view. Fresh installs and upcoming releases will not see this issue.

I would guess to separate native builds from others that require a native build to do development such as web assembly.

Check further down, you may have something called "Qt for Development", there lies additional entries for WebAssembly.
