Download your product's package file and your license file. They're in your email (active for 3 days after purchase), or always on your Downloads page.
Download Floe for free and install it — it's quick, straightforward and works just as you'd expect.
Open Floe like any instrument plugin — typically by adding a new track. It's usually listed under the developer Floe Audio.
In Floe, open Preferences, go to the Packages tab and click Install package. Choose the package file you downloaded in step 1, usually in your Downloads folder.
Floe then shows your product and asks for its license. Click Load license file and choose the license file from step 1, also in your Downloads folder.
Done. Your sounds are available immediately.
