Error re-installing Filemaker Server 12 - incorrectly Detecting a filemaker 7 install
I tried to re-install our Filemaker Server 12 on our Xserve but keep getting given an error stating that the install failed because it detected a filemaker server 7 install active. Following the suggestion in the knowledge base here (http://help.filemaker.com/app/answers/detail/a_id/7610/~/unable-to-install-filemaker-server-because-a-previous-version-is-incorrectly) I made sure to remove the offending plist. However, even after reboot the machine and clearing the java cache (as per the documentation) I'm still getting this error.
Any suggestions on what may be causing this problem? At this point, the most likely solution is to completely re-install the OS and start fresh, but I understandably don't want to do that.
