Help needed – install error "QtCore4.dll missing" with DAZ Studio 4.24 and v6 and Plugin Version 410

[MFindt]

Hi everyone,
I hope someone here can help me out. I recently switched to the latest version of DAZ Studio (6.25 is now installed as well to version 4.24),
and since I could no longer find the plugin installed, I tried to reinstall it (Version 410). Ever since the update, I've been getting the following error during install:

"QtCore4.dll is missing"

I don't think I can just roll back to the previous version anymore, since the database has already been converted. So I'm hoping to find a fix that works with the current setup.
I'm not sure whether this is caused by a missing system component, a plugin version mismatch, or something related to the update itself.
Has anyone run into this before and knows how to fix it? Any pointers or shared experience would be greatly appreciated!
Thanks in advance,
Michael

Quick update on this – I uninstalled version 6.25 and went back to a clean setup, and this time the Plugin Version 410 installed successfully without the QtCore4.dll error.
However, now I've got a new issue: the plugin isn't showing up under the Window menu in DAZ Studio, so I can't select or enable it from there.
Has anyone experienced this before? Any idea what might cause the plugin to install fine but not appear in the Window menu?
Thanks again for any help!
