I have had two people mention that they wanted the linkage program to run on Windows XP. One person had told me that it crashed and I then changed the install program to fail if the system is XP and not Vista or Windows 7.
Well, I finally got around to trying it and it appears to work. I just ran it on Windows XP SP2. The only thing that I am not sure of is the .Net framework version that is required if it is at all required. I think that the setup program is the only thing that actually uses .Net features but I have no control over it like I do over the Linkage program and its source code.
I will try to contact the people that wanted an XP version. Maybe someone can test it for me.
