The file MikesToolbox.docm file needs to be copied into the Word folder called STARTUP.
The STARTUP folder is found by clicking Start, then Run (or alternatively pressing the Windows key and R at the same time). You then need to type in the following: %AppData%\Microsoft\Word\STARTUP\ and click on OK. Or just copy and paste my example into the Run box.
Once the folder appears on your Windows desktop, copy the two files (the .DOCM and the .PDF) above into that folder. When you next launch Word, you will see a new menu item called Toolkit. You can launch the manual from within the toolkit.
Note: If you cannot find a STARTUP folder, the manual covers a quick fix that you can do from within Word to create one.
