I have tried to get the FTP Service 7.5 installed using genuine Microsoft setup files on a Windows 2011 SBS machine that's already running IIS 7.5, but none of these links below have worked--neither 32 nor 64-bit--due to a claim that these FTP services are only compatible with Windows 2008:
https://go.microsoft.com/fwlink/?LinkID=143196 https://go.microsoft.com/fwlink/?LinkID=143197
The error message states, "This version of the operating system is not supported. FTP Service 7.5 for IIS 7.0 can only be installed on Windows Server 2008."
I suppose I could go with a third-party solution but it seems to me Microsoft couldn't have left this feature out like that. Is there a way?
