Error 1402 during uninstallation (Could not open key)

Issue

When you try to uninstall an AutoCAD based product, you will get the following error:

Error 1402.  Could not open key: 
UNKNOWN\Components\Hex#\Hex#.  Verify that you have sufficient access to that key, or contact your support personnel.

 

Solution

The solution is to change the permissions of the following folder in the Registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components 

  1. Right Click on Components select permissions.
  2. Click Advanced button.
  3. Select the Owner Tab
  4. Under Change owner to:  Select Administrators (Group) and Click Apply.
  5. Then Select Check box Replace owner on subcontainers and objects and Click Apply.
  6. Go to the Permissions tab, select the Check box:  Replace all child objects Permissions with inheritable permissions from this object and Click apply.  NOTE:  The wording maybe a bit different depending on your operating system.
