1. Hold down the Windows key
2. Start typing DeNoise AI (NOTE: The last word is the letter A as in Apple, followed by the letter I as in Igloo. Many people mistakenly type the number 1, do not use a number)
3. Click the button that says Open File Location (if you do not see it in the menu, you may need to right-click DeNoise AI and select this from the context menu)
4. This will take you to a Window with two shortcuts in it
5. Right-click on the first link and select "Open file location"
6. The default path would be in C:/Program Files/Topaz Labs LLC/Topaz DeNoise AI/
