The type or namespace name 'UT' does not exist

I am getting this error, which is preventing me from playing my game and I looked online and I could not find the solution.

Assets/Standard Assets/Utility/SimpleActivatorMenu.cs(11,28): error CS0234: The type or namespace name ‘UT’ does not exist in the namespace ‘UnityEngine’ (are you missing an assembly reference?)

Any solutions?

  1. find what the UT package is (I’ve never heard of it… why are you using it? where did this code come from?)

  2. find out why you don’t appear to have access to it:
    — is it installed?
    — is it in different namespace? (i.e., missing using directive)
    — something else?

Just the same standard things you ALWAYS have to do when an identifier is not found.

Usually the error message in that file is regarding GUIText no longer existing. Did you modify this file to add whatever UT is? Standard Assets hasn’t been updated in a few years, and is no longer supported by Unity, so you’ve got to self support when using with recent Unity versions.
