I have had no issue with installing 11.4 on Windows 10 (tried 3 different PCs). However, the advice to use the 12.2 driver with Ink 2.3.2 is for me a wrong steer. The service does not auto start and the floating toolbar does not appear ("show floating toolbar" doesn't help) - according to Smart the floating toolbar is removed from version 12.3 so I should still be seeing it. The main issue though is with Ink - with that version it crashes Powerpoint 2016 the instant you start a presentation. Kill the Ink process and Powerpoint works. As I am testing things I decided to just go ahead and try the later driver (even though Smart don't state compatibility with 11.4) and having put on the driver 12.5 and Ink 4 (v12.5.768.0 and v4.0.890.0) everything works. I've lost the floating toolbar of course but gained the new toolbar (floating hand that Ink gives you).
