The "Player" button doesn't work.

Hi Vit,

The notice recommends that you download the new flash player because the software recognizes that the flash player is missing on your system. Storyline 2 is outdated software, At the time of its release, this error message indicated the correct course of action. Because Storyline 2 relied on Flash to preview your project, it cannot play the  project without the flash player. This is why your player button is not working.

There are sources where you can download and install flash on your system. Once you've installed the flash player, you can preview your project in Storyline 2. You may see several warnings from various security packages about loading flash, but it can be done. I had to do that a while back to view an obsolete project that I was attempting to re-create.

Instead of continuing to use Storyline 2, your best option is to update to Storyline 360.
