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 so please follow all the instructions carefully.

   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 or Network > Macintosh HD or use Finder > Go > Go to Folder...
      2. Then into Library, and then Application Support.
      3. In the Application Support folder, find the SketchUp # folder, and then move it to bin.
         
         
         For SketchUp 2025 the folder will simply be "SketchUp 2025".
         
   4. Delete the SketchUp folder from your user library:
      1. Now head to Users, then your user name, then click the hidden Library folder.
         
      1. 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 move it to bin.
   5. Delete the SketchUp application:
      1. No head back to Macintosh HD > Applications.
      2. Find SketchUp # folder, and then move it to bin.
   6. Delete the plist file:
      1. Once again head to your Username folder in the Users folder.
      2. Then head into the hidden Library folder, and then Preferences.
      3. In the Preferences folder, drag any of the following files, if present, to the trash:
         If you only use one version of SketchUp delete all plist files connected to SketchUp but if you regularly switch between versions just delete the files of the year you are uninstalling. If you are uninstalling due to errors in SketchUp it is best to delete all plist files regardless of multiple versions.
