I can't find asset library in my enscape menu.

Hey vimut2020 , our Asset Library is only available in our latest previews so far. You probably have our latest release installed instead.

To install our latest preview:

-> Head into the about window by clicking the About button -> Click Visit download area -> Click on the hyperlink right in the first sentence below our Download button -> Now that you're on our preview page, just click Download -> You now have our latest preview which you can simply install, as it will overwrite your existing (latest) release.
