Installed Filemaker Pro v9 on my Windows Vista Machine. No matter how many times I uninstalled and reinstalled or how many settings that I changed - disabled services - ran in compatibility mode (XP) - installed in Compatibility mode (XP) - spoke with Filemaker Tech support - posted on Filemaker and Vista Forums for help - nothing worked. Tech support finally hooked me up with a copy of v8.5. It's up and running. Wish I could get v9 to work!!!
