Yeah, so when I got it originally my friend had the demo on his hardrive and I just copied it from him. Unfortunately he did something weird to it, or it downloaded wrong where the final cut and After effects files seemed to be both mixed in, and thats why the installer was greying things out and the "other applications" box wasn't working right. I then re downloaded the demo on their site, but the same thing happened for some reason. Im sorry to say that I think it was just luck that it worked eventually, I just downloaded it a third time and the installer did what it was supposed to. What I meant by support files was the final cut aspect of it, deleting whatever adobe parts I got originally. Just FYI then, if you want to tell it to install at the top of your hardrive, or just on the desktop, the correct folder to drag the folder titled Twixtor5fxPlug into is Library--- Plug-ins ----FxPlug and the twixtor folder should contain Twixtor5.fxplug and the Twixtor5FxPlugManual folder. Now David said above he copied it to library--application support--final cut pro system support--plug ins, and maybe that works to, but the way I described is how twixtor installed it when it worked eventually, and it showed up in the video effects tab under its own name. In the end, just try re downloading and re installing and restarting final cut, being sure to delete whatever twixtor files are there if it doesn't work, because I think it just comes down to the computer deciding to work, since fcp 6 really is unfortunately outdated at this point when it comes to HD footage and support for these kind of additions. Good luck and if you have more issues with it im happy to troubleshoot back.
