My Man !: it's in D:\bb\Data\Installers.
However running the installers, rebooting Windows (and BIAB) doesn't show them, other then that there's a new (was there already) folder on my boot disk: C:\pdf995.

Alas BIAB still shows the error message (see above, OP) when you press 'Print to PDF'. It won't install ... Thnx, F
