is there an adobe extension manger for 64 bit ?

I have PC 64 bit .. I was having adobe photoshop cc 14.1.2 with extension manager 32 bit , but when I downloaded the version of adobe photoshop 15.0.8 I noticed that there is no extension

So I was asking if there is an extension manager I can download for 64 bit ?

I hope anybody can answer me

thank you
