QCAD and QT6, Windows

I have tried to run the Snapshot (3.31.2.4) on my Win7-64 pc. It installs but QCAD refuses to start. Is my Windows too old to be compatible?

Unfortunately, Qt 6 does not support Windows 7:

But we will still provide Qt 5 packages for the foreseeable future.

Thanks Andrew.
Too bad I like 7, and hope I can keep it for a while…
