HOTFIX: The "Size (bytes) field displays the file size as Damaged when you view the file properties for an ActiveX control in IE7
Consider the following scenario. You download an ActiveX control. You view the file properties for the control in the Downloaded Program Files folder. You click the Dependency tab in the Properties dialog box. In this scenario, the Size (bytes) field may not display the file size in bytes. Instead, the Size (bytes) field displays the file size as Damaged. This problem occurs if Windows Internet Explorer 7 is installed on the computer.
Note By default, the downloaded ActiveX controls are stored in the C:\WINDOWS\Downloaded Program Files folder when you install the control.
