Apparently you will have to re-download / re-install everything.
A clean install wipes everything.
The fact that you have some items ( programs etc ) showing indicates that you did not format the HDD during the clean install.
I recommend that you work with what you have now and collect all needed programs, drivers
etc. and store them on a separate Drive or Partition. Than start a new clean install and be sure to format the HDD, or you may have more leftovers which can cause more problems.
