Hi, Just recently uninstalled FMS_11 so I can install FMS_12 and in doing so I seem to have created a problem for the Windows IIS server. Web applications not using filemaker return a 500.19 error which has something to do with the applicationHost.config file. (See attached image). I have also attached a copy of the file in question (applicationHost.config).

 

Any help here would be greatly appreciated.

If you are not using IIS except for FMS then you can try removing the web publishing role from Windows, reboot and add it again.  All before installing FMS12
