What version of KeyView for Lotus works with Windows 10 64bit?
The software was developed for 32bit operating systems. It won't work in any of the 64bit versions of Windows that have been released. The compatibility mode doesn't help either, because I've tried to install it with Windows XP compatibility and it refused giving the same error.
You will need to install VirtualBox in Windows 10, and then Windows XP inside Virtualbox.
