VSTA Audio Engine -- where do I go to reinstall?

Deleted VSTA audio engine because I couldn’t get any sound, but now Dorico is failing to boot. What do I do to reinstall VSTAudioEngine_64?

Thanks all, and Happy New Year!

note: accidentally deleted file instead of uninstalled.

Just run the whole Dorico installer again, that won’t do any harm.
If you then still can’t get sound out, please create a new piano project, enter some arbitrary notes and then choose from the menu ‘Help > Create Diagnostics Report’. The corresponding zip file please attach here. Thanks and a happy new year to everybody
