KB0004 - Radium.ocx failed to register

The information in this articles applies to:

•	Living Cookbook v1.3, v1.4, v1.5
•	Windows XP

Symptoms

When you attempt to install Living Cookbook, the following error occurs:

Error 1904.module c:\program files\living cookbook\radium.ocx failed to register HResult. Contact your support personnel.

If you attempt to run Living Cookbook, you will get the following error:

Application terminated. Error: Error calling external object function enablebutton at line 34 in function of _enabletoolbarbutton of object nfc_u_tabpg_task_calendar.

Cause

Radium.ocx is a resource file that contains the Living Cookbook toolbar controls. Some users' PC are configured in a way that prevents the Living Cookbook installation program from installing this component. The two most likely causes are: 1) You are not a member of the Local Administrators group; or 2) The Local Administrators group does not have "Full Control" rights to the HKEY_CLASSES_ROOT branch of the registry. This knowledge base article will address both possibilities.

Resolution

1.	Click your Start menu, point to Control Panel and click User Accounts.
2.	Select your user account from the list and click Properties.
3.	Click the "Group Membership" tab.
4.	Click "Other".
5.	Select "Administrators" from the list.
6.	Click OK to close the user properties window.
7.	Click OK to close the User Accounts window.
	Now, let's set the registry permissions. Try the following:
1.	Click Start and then click Run.
2.	In the Open box, type REGEDIT and click OK.
3.	When the registry editor opens, click HKEY_CLASSES_ROOT.
4.	On the Edit menu, click Permissions.
5.	Select "Administrators" in the "Group or user names" list.
6.	Make sure that "Full Control" is checked in the "Permissions for Administrators" list below. If it is not checked then check it now and click Apply.
7.	Now, click Add...
8.	Enter your user name under "Enter the object names to select". Enter your user name exactly the same way that you do when you log on to Windows.
9.	Click OK to close the "Select Users, Computers or Groups" window.
10.	Your user name should appear in the "Group or user names" list. Make sure your user name is selected.
