restart the windows machine then look at system control services.
is the service "Filemaker Server 9" (or 10) still running or not? *NOT* running and NOT in the list? That´s good.
To remove fms10 from the programs control you can use the "Windows Installer Clean Up", you can get it at ...
(maybe there is a english description too, i dont know)
After done this, you can delete the Filemaker Servers Directory. But ensure you have backed up your data files before.

I checked the services control utility, and no FileMaker services (except for Bonjour, if that counts) are installed anymore. But the FMS10-Admin Console and FMS10-APPLICATIONSERV applications still appear in the installed programs control panel. I used the Windows Installer Clean-Up utility, and neither of these applications appear in that utility's list, so I cannot remove them that way, either. Trying to uninstall them using the Windows Programs control panel still results in the error "Cannot completely uninstall application." I deleted the FileMaker Server program folder, so that can't be causing anything. I'm out of ideas...
Edit: I just thought of something. FileMaker Pro 8.5 is also installed on this machine. Could that be causing this issue?
