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/
