What´s wrong ? Thanks
Which version of photoshop cs6 do you have?
Perpetual license 13.0.....
What does "(I haven´t installed on program files as most people use to do)" mean?
You shouldn't have to use the additional plugins preference if you put the plugins into the 64 bit version of photoshop cs6's plugin folder, which is where they should go.
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Plug-ins
All but the lighting effects and Optional Multiplugin are file formats which would show in the open or save dialogs.
Lighting Effects would be under Filter>Render>Lighting Effects Classic
There should also be Filter>Other>HSBHSL (included as part of the OptionalMultiPlugin)
