I can't install Kidspiration on Windows 10. Installation starts, it finishes; but Kidspiration is never loaded, without even a message.
I've downloaded the trial version from the official website, and installed it on Windows 10 operating system running on x64 architecture. The trial completed successfully and I was able to launch the application.
The default installation path is: C:\ProgramData\Kidspiration 3
Obtain the installation package and install it and it will work.
