sorted, also recovered z3ta+, because i have Sonar X3 and Sonar Steam Edition installed already the vsts for the Steam version are in a different location to normal..
I added the 2 folders below to get the 64 bit Rapture Session VST3 and the 32bit version of z3ta+
C:\steam\steamapps\common\cakewalk\vstplugins\z3ta+
C:\steam\steamapps\common\cakewalk\x64\vst3
(replace C:\steam with wherever your steam library is installed)
If anyone else is using steam version also and has similar issue :)
