Most VST's are 32 bit most will work fine in BIAB there are and will most likely be an increasing number of 64 bit VST's, for these you will need JBridge to use in BIAB even if your system 64bit as BIAB is not 64bit.
((These 64bit VST's wont need JBridge on your system in say Cubase or Sonar ect 64bit))
As mentioned BIAB (32bit will work fine on your new 64bit system), I run BIAB on 64bit Win 8.1
