Studio One Producer V2.5 (x64) and Softube Saturation Knob

Just curious if anyone knows if the Softube Saturation Knob is 32 bit only?

Doesn't show up in my effects list in the 64 bit version of S1.
But, in the 32 bit version of S1 it is there.

I does show up in the installed extensions on both the 32 bit and the 64 bit version of S1.
Hence my reason for asking.

Hi, It's showing up fine here on bus effects drop down (vst3 so it's at the bottom) and in the browser.

Showing up fine here too in 32 and 64 bit 2.5 Pro.

Showing up in 64 bit 2.5 Pro.

Sounds like I might have a problem then.

I'll try uninstalling and re-installing it, maybe it'll show up then.
At least now I know it SHOULD be showing up.
Thanks people's

I have first uninstalled theSoftube Saturation Knob, then both the x64 & X86 version of S1.
Then I re-installed S1 x64 first and installed the Softube Saturation Knob.
Still it does not show up.

Then I installed the x86 version of S1 producer, checked in it and the Saturation Knob plugin shows up there.
Guess if I want to use it I'll just have to use the 32 bit version of S1.

Does anyone know the default installation folder that S1 and/or Softube install this VST to?
I have checked in every VST folder I can find (know about), I don't even see the plugin' DLL anywhere.
