Maybe you should uninstall those 3 products (the software, not the sounds libraries) and use the Import feature of ST3 to bring all their libraries into ST3. Then you can use all the instruments there, layer them etc. NB If you have ST3 MAX, I think that you already have the ST2 XL library available.
I did indeed have the stand-alone versions. however they all quit working at the same time
so I was forced to go to the (new) SampleTank3 to use it's player to continue to use these products. At that point I deleted the non working players...IK's solution at the time. You believe those players work now without the registry error? I already use the libraries as you suggested in ST3.
