Quote - If you ran the update with Poser running, it my be corrupted or an incomplete install.

Uninstall Air then reinstall it.

 

I clicked on the update while in Poser (P2012 Win 7 64 bit) without thinking but it updated and everything was fine but I guess it may depend on what Poser was doing at the point the update was performed. 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
