Download the latest version of !SEMTools here:

After download:

  1. Don’t open the file
  2. Find it on your computer (usually in ‘Downloads’ folder)
  3. {Optional} Copy the add-in file or move it to a folder on your computer where it won’t get lost or won’t be accidentally deleted, i.e. C://!semtools/ folder
  4. If the file is locked, unlock the file after opening its properties with the right mouse button.

Why unlock the file? Windows blocks files downloaded from the Internet by default, and !SEMTools tab may not appear in Excel if the file stays locked. This is universal for all .xlam add-ins, proof.
