You know, you can extract the files (by the installer) to any folder you want to, and copy the files from there to your game folder later.
So you maybe can see, if the installer work at all or how big extracted files are.
Just as a hint.

Ah ... I'll be accepting today's 'Moron of the Day' award ...
Thanks VERY much EJGr.Ost_Caspar for your advice. It led me to the real solution because it made me check out where my files ACTUALLY are.
The 4.10 installer was defaulting to my C: drive (the standard installation path for IL-2 46) but I'd actually installed the app on my D: drive (I have a small SSD as my C: drive so I was saving space on it, my D: is a Velociraptor). It's been so long since I did the installation that I forgot! My sincere apologies for wasting your time. Suffice it to say all is now well and I have a fully operational 4.10 version of IL-2.
Sincere thanks to yourself and Team Daidalos for continuing to develop and support this amazing application that I've been using since the beginning so many years ago!
