If you install CADWorx 2017 and forget to add a feature, such as P&ID or Specification Editor, you cannot modify the install to add the missing feature.  If you go into Programs and Features and select modify and attempt to modify a feature you will receive one of a few errors.  If you are modifying a feature that requires a serial number you will receive an error stating that your serial number is invalid; this is not the case.  If you are modifying a feature that does not require a serial number the program will error out and show you a text file with a log showing the failure.


To get around this issue you just need to fully uninstall CADWorx and reinstall it choosing the proper features.
