The Fluid mask installer doesn't recognize Photoshop 6. I selected other and tried to put the “Vertus Fluid Mask 3” folder that contains the files dbghelper.dll & FluidMask3.8bf into the Photoshop 6’s plugins directory. It’s not available within Photoshop.
It does however function as a freestanding program so I know it works on the computer. It also worked very well under CS5.
I’m sure Vertus will get around to upgrading, but I’d like to be able to use it with my current projects and not have to wait for them
UPDATE: The above procedure works for the 32 Bit install of CS6... Not with the 64Bit.... would like it to work with 64bit since I edit some sizable files
