To test, put this in a bat file "Snagit.bat" and run it: Snagit.bat content =[ start "Snagit" "C:\Program Files\TechSmith\Snagit 2019\Snagit32.exe" "%1" ] (inside the brackets only, single spaces before/or after all double quotes)
From Excel, you can hyperlink to the bat file, although IMO, hyperlinking is much better behaved from . . . Open Office's Calc program.
From VBA? I've always steered clear of any macro that contains a valid internet or local address, so you're on your own.
