App Store says an app is installed, but it isn't I've installed a new primary SSD drive on my mac, now I'm trying to download a few apps that I've already installed on my previous HD, but app store keeps saying they're already installed. But they are not.

Is there a way to tell Apple's App Store that these apps are not installed?

I've already tried the solution on the thread: App Store thinks apps are installed, but no success.

My old HD is still connected to my MBP, but as slave. If you guys need further info, just ask.
Just fixed it. Sorry for the noise, guys.

This thread fixed it:
