Thanks for posting.
On the Windows side, these are the system requirements:
Windows Server 2003 Standard Edition sp2
Windows Server 2008 Standard Edition sp1
Windows Vista Business sp1
WinXP Pro sp3 is listed in the system requirements article/tech specs because this is a suitable Operating System for the Admin Console (you can configure the remote Admin Console on a Win XP machine, just not the server software).
Here is the link to the FileMaker Server Tech Specs:
Hope this helps.
What prevents the server from being installed on XP Pro?
The installer will prompt you if the OS requirements are not met that it can not be installed.
Hope this helps!
I understand that, but what is the actual limitiation of the OS that makes 10 not able to work?
Unfortunately, I will not be able to answer this question as it is FileMaker policy not to comment on questions pertaining to proprietary information.
I just haven't seen any apps not work in XP Pro that worked in 2003.
