I have a Basic MSI project for which the checkboxes for 'Show the Windows Installer log' were deleted. Seems like a simple matter to add them back in. I can easily do one... but when I try to add that checkbox to another SetupComplete dialog I can't use the property ISSHOWMISLOG because "Another Checkbox is already using the property ISSHOWMSILOG. Please enter a different property." How can I get back to the way it is for other Basic MSI projects where all 3 SetupComplete dialogs use that property?
