Running objectdesktop_setup.exe, offers a choice of a number of programs to install. I chose Fences, Multiplicity, and Spacemonger. The first two installed, as independent programs, which I can start from their own icons. Spacemonger however did not behave this way. While objectdesktop_setup.exe was still live, it invited experimenting with Spacemonger, and offered some introductory text. All of that worked fine. After closing Spacemonger, there was no icon, and the program was not listed on the start menu. I could start it again by running objectdesktop_setup.exe again, and selecting Spacemonger for installation.
