Problem

Upon completing a service pack (SP) upgrade of SOLIDWORKS, older installations of SOLIDWORKS will sometimes display the error: "Error 1706. No valid source could be found for product SOLIDWORKS 20XX SP0X. The Windows Installer cannot continue".

error 1706 no valid source could be found for product SOLIDWORKS. The Windows Installer cannot continue.
