I am installing Windchill11.0. and all of the packages are latest version from PTC software download web site. when attempting to copy service pack to the staging folder, it says "Invalid CD selected. Please select another CD". And all of the others copy correctly. the service pack I download is “PTC Windchill 11.0 Service Pack - Critical Patch Sets Bundles M020 =>> MED-61006-CD-110_M020_M020-CPS04-Bundle.” any ideas?
