Symptoms when you install and uninstall a program, the "Add/delete program" tool in "Control Panel" may not correctly display the installed program. The currently installed program box may only contain a single text string, or a large blank area may appear before the program item. Other display problems may also occur, such as not listing any programs. In addition, one of the following error messages may be displayed:
Message 1
An unexpected error occurred. class not registered
Res: // appwiz. Cpl/ListBox. HTC
Line: 225
Message 2
The object does not support this attribute or the method Res: // appwiz. Cpl/Default. HTA
Line: 75
This problem may occur if the uninstall program of a program mistakenly deletes the registry key used by windows and the Add/delete program tool.

If the "Add/delete programs" tool displays the user interface of the dialog box but does not display any installed programs, check whether the following items exist in the registry:
Hkey_classes_root/CLSID/{352ec2b7-8b9a-11d1-b8ae-006008059382}/inprocserver32
If this registry entry is lost, copy the following text to a text file, save the file with the. Reg extension, and double-click the file on the affected computer to return the correct entry.
For Windows Registry Editor Version 5.00:
