I 'thought' it came with Object Desktop but, like other's have found that the 5.10 version didn't work in 10.
So, somehow - and for what reason I can't recall, I downloaded a 'public' version which works without any problem.
Please DO NOT INSTALL IP on Windows 10.
I strongly recommend against the use as you WILL end up with problems.
There is a very good reason we block the installer, please trust us!
