- I have a Unity Pro license, but I cannot find the Flash build option
- I had a Flash add-on license attached to my Unity Pro 4 license, but when I upgraded to Unity 5, I cannot deploy to Flash any more
Unity supported Flash in 4.x and earlier, but this is no longer the case with Unity 5.x
Unity stopped supporting Flash in April 2013. It is not available to use in Unity 5.
If you already have a Pro license for Unity 4.x or below, which includes the Flash add-on, you will be able to create and build projects to Flash within those versions of Unity.
See this blog for more information on support for Flash in Unity.
