Click the Start menu > Control Panel > Add/Remove Programs > SketchUp #.

To uninstall SketchUp, select uninstall or Modify > Remove. When asked if you'd like to remove SketchUp, click Yes.

If you are having problems with SketchUp, you can try the 'Modify' option, which begins the process of reinstalling the program features that were installed during the last installation. This can fix any application files that were corrupted (this doesn't affect or fix your SketchUp drawing files, the SKP files). If that doesn't work, try uninstalling and reinstalling SketchUp.

1. Please Note: A clean reinstall is not a standard removal and re-installation of the program. There are additional hidden files and folders to be removed.

   To Clean uninstall:
   

   1. Quit SketchUp. (If you have more than one instance of SketchUp open, make sure you quit all instances of SketchUp.)
   2. Open a Finder window.
   3. Delete the SketchUp folder from the main library:
      1. In the left pane of the Finder window, click Macintosh HD.
      2. In the right pane, click Library, and then Application Support.
      3. In the Application Support folder, find the SketchUp # folder, and then drag it to the trash.
         
         
         For SketchUp 2024 the folder will simply be "SketchUp 2024".
         
   4. Delete the SketchUp folder from your user library:
      1. In the left pane of the Finder window, click Users, then your user name, then click the hidden Library folder in the right pane. To show hidden folders press Command + Shift + . (Full stop/period)
      2. Open the Application Support folder.
      3. In the Application Support folder, find the SketchUp # folder, and then drag it to the trash.
   5. Delete the SketchUp application:
      1. In the left pane of the Finder window, click Applications.
      2. In the right pane, find SketchUp # folder, and then drag it to the trash.
   6. Delete the plist file:
      1. In the left pane of the Finder window, click your user name.
      2. In the right pane, click then hidden Library folder, and then Preferences.
      3. In the Preferences folder, drag any of the following files, if present, to the trash:
