How to Clean Install or Uninstall Plex-Earth

Applies to: any Plex-Earth version Audience: End users, IT Managers

Overview

A clean installation removes all Plex-Earth files, settings, and traces from previous versions before reinstalling. This is recommended when:

• You are experiencing persistent issues that standard troubleshooting has not resolved
• You are upgrading from an older version and want to ensure no conflicting files remain
• You have been asked by our support team to perform a clean reinstall

💡 Just need to uninstall? Follow Steps 1–5 only and stop there. Steps 6 and 7 cover the reinstallation.

⚠️ Before you begin: Make sure CAD is fully closed before starting. Having CAD open during this process may prevent some files from being deleted correctly.

Step 1: Uninstall Plex-Earth from Windows

From Control Panel:

1. Open Control Panel → Programs → Uninstall a Program
2. Search for Plex in the list
3. Uninstall every Plex-Earth version currently installed on your workstation

From Windows Settings:

1. Open Settings → Apps → Installed Apps
2. Search for Plex
3. Click the three dots next to each Plex-Earth entry and select Uninstall

⚠️ Make sure to uninstall all Plex-Earth versions, not just the most recent one. Leftover installations from older versions are a common cause of persistent issues.

Step 2: Unload Plex-Earth from CAD

1. Open AutoCAD or BricsCAD 

2. Type CUI in the command line 

3. Go to Partial Customization Files 

4. Find and unload any Plex-Earth entries listed there 

5. Close CAD

Step 3: Remove Plex-Earth .cuix Files (Autodesk Only)

1. Close CAD if it is still open
2. Open File Explorer and navigate to:

%appdata%\Autodesk

3. Open the folder for your CAD product and version, for example:

C:\Users\User\AppData\Roaming\Autodesk\AutoCAD 202X\R2x.0\enu

4. Find and delete all Plex-Earth .cuix files, such as:
   • pxearth25-r0.cuix
   • pxearth26-r1.cuix
   • Any other Plex-Earth .cuix files

⚠️ The .cuix file location differs depending on your CAD product (AutoCAD, Civil 3D, etc.) and version year. If you use multiple CAD versions, repeat this step for each one.

Step 4: Delete Plex-Earth Program Files

In the Windows Search bar on your taskbar, type each of the following addresses one at a time and press Enter. In each location, search for any Plex-Earth or Plexscape files or folders and delete them:

• %ProgramData%
• %ProgramData%\Autodesk\ApplicationPlugins
• %appdata%
• %appdata%\plexscape\Plex-Earth
• %programfiles%
• %programfiles(x86)%

💡 Tip: In each location, type Plex in the File Explorer search bar to quickly surface all relevant files and folders.

Step 5: Delete Temporary Files

1. In the Windows Search bar, type %temp% and press Enter
2. Select all files in the folder and delete them
3. Repeat with temp (without the % signs)

ℹ️ Windows may show errors when deleting some files — this is normal. Skip any files that cannot be deleted, as they are likely in use by Windows or another running application.

✅ If you only need to uninstall Plex-Earth, you can stop here. Steps 1–5 constitute a complete uninstallation. No further action is required.

Step 6: Download and Install the Latest Plex-Earth Version

Download the latest Plex-Earth version from the download page: https://plexearth.com/download

If you need to install a specific older version, you can find all available download links here: Plex-Earth Download Links and Compatibility

⚠️ Make sure you are downloading the version that matches your license key. Installing the wrong version will result in an activation error. If you are unsure which version your license is for, check your purchase email or the Plex-Earth Console.

Step 7: Open CAD and Verify

1. Open your CAD application
2. Confirm that the Plex-Earth ribbon appears correctly
3. Sign in and verify that Plex-Earth is working as expected

If the ribbon does not appear after a clean installation, see: Plex-Earth Ribbon Missing, Empty, or Not Working
