This error will occur on Windows Vista and Windows 7 machines when User Account Control (UAC) is on and VB6 tries to write to an inaccessible part of the registry.
You will see this error message when an ActiveX control is used for the first time. This may be when a project using the control is opened, or when the control is selected to add to the Toolbox.
After the initial failure, VB6 will select an alternate registry location to write to, and subsequent uses of the control will not produce the error. Back to Top
