Final Cut Pro 10.0 is already installed and was not purchased from the Mac App Store

Same thing for me and weirdly I should never even have been able to purchase as my Mac has a Radeon 2600 in! I was given no warning about incompatibility and actually it seems to work pretty well. So I'm doubly worried about updates as I have the 'install' problem and also an upgrade might fail due to the wrong graphics card.

I also have this problem with Motion, but not with Final Cut.

It bothers me, as even though both apps work, I'm not sure I can reinstall at later time should it be needed, or that I'll get software updates when they're available.

I am having problems with both Motion and Final Cut. Final Cut is showing that I purchased it but gives me a similar error as above (that it wasn't purchased on the App Store). Motion, which I purchased through the app store last week, is not showing that I purchased it at all.

I sent in a customer service request here: http://www.apple.com/support/mac/app-store/contact.html?form=account#

Hopefully I'll hear back sometime this week as to why this is happening. You all should do the same if you haven't already.

I am having this problem with FCPX as well -- I think it happened after I upgraded to 10.6.8.

I have the same issue. I contacted Apple who assure me that even if I click the 'buy' button, I won't be charged again. I tried it and you get a message saying that the application has already been purchased and installed, and that you should use software update to check for new versions.

Hopefully whatever's wrong will sort itself out over time, otherwise I'll chase it up again first time there's an update I can't install.

Move your FCX program from the Applications folder to the Trash to fix the problem.

I have the same problem and the kicker is I can't download and install FCP X on the other Macs I own. This is a feature permitted by FCP X, as I understand the licensing agreement. For example, you can't download the app onto your laptop.

I suspected that might be the case but to save bandwidth, I've just copied FCP from one machine to another.

I'm waiting to see if the problem just magically goes away once I update to Lion.

Tried slanz's suggestion and trashed FCPX (having backed up, of course). Had the pain of downloading it again, but it now shows up as 'Installed' on the App Store.

Also, I opened Motion 4, as suggested here http://www.dvcreators.net/make-sure-you-read-this-before-installing-final-cut-pr o-x-motion-5-or-compressor-4/

Can only think that App Store got confused with the two versions of FCP on the system, and second time round FCP7 was already in the Applications/Final Cut Studio folder, but that's just a guess.

Can confirm that moving FCPX application to trash and simply reinstalling worked for me as well. Now it lists as INSTALLED in the Mac App store.

Same problem here ... Easy fix.

Unistall your FCPX from your computer .

Then click install from the apps store et voila.

I do not know what happen when I download the FCPX initially , but I got the message : " not downloaded from AppStore " .

Probably a glitch from AppStore ..

Same problem here too. Makes me leery of buying apps via the Mac App Store. Unfortunately, there is no other way to get FCPX, Compressor or Motion, except through the Mac App Store.

I have a slightly different issue. I had a DEV copy of FCP X I got from a friend. Ran it on my Mac Pro fine. Decided to buy it for myself so I would get all the legal updates and all. Uninstalled the DEV Preview copy, and when I try to purchase through the app store, I get the message that my video card does not meet the minimum requirements. I have an ATI Radeon X1900 XT 512 MB. And the DEV copy ran just fine. I guess I need to call AppleCare...

I had the same problem with not being able to upgrade to Final Cut Pro 10.0.1. The easiest fix is to delete the Final Cut Pro app from Applications, then re-download Final Cut from the App Store. It then installed the latest version 10.0.1 with no problems.
