Hi Waynec444:
First, create a shortcut to the main executable (.exe file) on your Windows desktop. Browse to the .exe file in File Explorer, right-click and choose either Pin to Start to add a tile to your Win 10 Start menu or **Send To | Desktop (create shortcut)**if you also want to create a desktop shortcut. I've used the executable for my Firefox browser as an example.
If you created the desktop shortcut then go to your desktop and rename the shortcut to any name you wish (mine was originally named firefox.exe -Shortcut), right-click, and choose Pin to Start to create the tile.
To add the shortcut in your scrolling list of installed programs on your Start menu see Ed Bott's instructions in Windows 10 Tip: Add Custom Shortcuts to the Start Menu.
If that doesn't help let us know your Windows operating system and the name of the installed program you'd like to add to your Start menu. You've posted your question in the Windows Vista board of this forum and support for this OS ended on 11-Apr-2017 - if necessary, we'll ask a Forum Moderator to move your question to the appropriate board.
