Sonar Platinum
Operating System: Windows 10
I used the command centre to download the Engineering FX Suite.
I then located the Setup file and installed the Suite.
I am able to locate it's presence as installed in Programs and Features
I am unable to find the Suite in the VST3 FX Rack menu or locate it under Audio FX VST3 menu.
I want to use the LP MB and LP EQ features for mastering. 
I checked my graphics driver and have the latest one installed: GeForce 9400 GT.
 
Could it be that I'm using 32bit
 

I would not have thought that 32bit would be an issue.

Note: the GeForce 9400 GT has openGL 2.1 but These plugins do use Opengl 3.2 and may not be supported by your graphics card.

Did you do a scan of your VSTs. 

Thank you for the answer, I assume you are talking about a scan other than the one Sonar does when starting up? If not, then I am unaware of it, if true could you please point me to the scan you refer to.
I will have to look into the OpenGL 3.2 issue.

Is it possible to upgrade the GeForce 9400 GT with a driver that supports 3.2? I would seem possible based on a GeForce thread I just read? I am an absolute novice when it comes to graphics cards.

If you go into preferences, file and VST settings do a reset and scan, that should do it.

However, it might be moot due to your card's OpenGL level below what is required.

The level of OpenGL is dictated by the physical card itself.  Therefore you would need to upgrade the card itself to at least a GT 420 (Which supports OpenGL 4.1)

Wow thank you you are a genius promidi, I followed your advice and did a VST reset, it worked! with my old OpenGL2.1 and all. It seems that I don't have to upgrade my graphics card just yet :-)
