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.
The solution is to change the permissions of the following folder in the Registry:
- Right Click on Components select permissions.
- Click Advanced button.
- Select the Owner Tab
- Under Change owner to: Select Administrators (Group) and Click Apply.
- Then Select Check box Replace owner on subcontainers and objects and Click Apply.
- 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.
