Experiencing crashes, corrupted workspaces, or persistent glitches with your CAD software? Often, performing a clean uninstallation and reinstalling the software is the fastest way to resolve these critical errors.

This guide provides a straightforward, step-by-step process to completely remove IJCAD from your Windows 11 machine. We will also cover the vital step of wiping residual AppData configuration files—a common culprit for carrying over old bugs into fresh installations.

Step 1: Standard IJCAD Uninstallation

To fix immediate app performance issues or simply free up system space, start with the standard Windows 11 removal process.

1. Right-click the Start button on your Windows taskbar.
   

2. Select Installed apps from the context menu.
   

3. Locate IJCAD in your application list. (You can also type "IJCAD" into the search bar at the top to find it faster).
   

4. Click the three-dot menu (...) on the right side of the IJCAD listing and select Uninstall.
   

5. A confirmation pop-up will appear stating that the app and its related info will be uninstalled. Click Uninstall again.
   

6. If prompted by Windows User Account Control (UAC), click Yes.

7. The IJCAD uninstaller dialog will launch. Click Yes to proceed.
   

8. Wait for the automated process to finish. Once you see the final completion dialog, the core application has been successfully removed from your system.

Step 2: Clear Leftover AppData (Crucial for Clean Reinstalls)

Even after a successful standard uninstall, Windows leaves behind user configuration files (like your customized CUI settings). While this is helpful if you are simply upgrading versions and want to keep your UI layout, these leftover files are often the root cause of persistent CAD errors.

If you are uninstalling due to software instability, you must delete this hidden folder to ensure a truly clean slate.

How to Delete Residual Configuration Files

1. Open File Explorer.
2. Click View in the top command bar.
   
3. Hover over Show in the dropdown menu and verify that Hidden items is checked.
   
4. Navigate to the following directory path:
   C:\Users\(Your Username)\AppData\Roaming\IntelliJapan
   (Note: Replace "(Your Username)" with your actual Windows login name).
5. You will see folders for every IJCAD grade previously installed on your machine.Select the folder matching the grade you just uninstalled.
6. Right-click the specific version folder you wish to purge and select Delete (or click the trash can icon at the top of Explorer).
   

⚠️ Professional Warning: Be extremely careful to only delete the folder for the version you just uninstalled. If you accidentally delete the settings folder for an active, working version of your CAD software, it will reset all your toolbars, shortcuts, and custom UI elements to their factory defaults upon the next launch.
