CS5 Filter Gallery is Disabled

Question

I work on a 64 bit Windows 7 environment. CS5 Filter Gallery along with some other contents (such as artistic) are greyed out. How do I enable them?

Misunderstandings?
It sounds like you're thinking uninformed users are just picking deep data formats by accident (or by the "if 8 is good then 16 is better" school of thought), then can't understand why their filters don't work, so the solution is just to advise them to work at 8 bits/channel and all will be great.  That just seems wrong, because 16 IS better!  In this day and age of powerful computers and output devices with ever more capability, advising people to use 8 bits can lead to to posterized colors and other problems in their artwork where none need exist!  Who, if not a creative person, will tweak and retweak their pixels until they're just right.  Imagine all that accumulated round-off error...
Isn't your focus with Photoshop full version supposed to be on high-end image editing?  Best possible results?
Perhaps you believe there are two (non-overlapping) types of people...  Type A likes quality and Type B is creative and paints sloppy pictures, and never the twain shall meet?
Hate to burst your bubble, but I BOTH care about quality and get creative. 
Some time ago I tried to use the Glowing Edges filter in a general purpose action - and learned that it only works on 8 bit data - so I had to do backflips and ultimately switch to the Find Edges filter, which for some reason you DID choose to update to handle deeper data. It would have been easier if I could just have kept using Glowing Edges, and I won't forget that your choice to save a little money cost me more in development.
Not long ago I chose to paint over a photo with the Mixer Brush in 16 bits/channel mode, and Photoshop was fast enough on my machine to support that choice.  But when I chose to add a few effects to some parts of the image I had to make a copy of the document, switch to 8 bits, and do the job.  Doable, but a bit of a concentration breaker, and the results were, of course, somewhat limited in quality.
I think a lot of people just accept that things (don't) work as they are and learn to avoid trying them.  Does that mean that the product is right?
Do you have telemetry telling you what parts of Photoshop people actually DO use?  If not, perhaps you might consider implementing some.  But alas, that opens the possibility of abusing the results (as Microsoft does).  Solid leadership is what's needed.  Hey, SOMEONE thought all those 8 bit filters were useful and put them in Photoshop in the first place!
I guess by now you can see that I'll never buy the "users haven't beaten down our doors for it so we're not bothering to update the old filters" school of thought.  But I'll concede that I must be alone in this, because few others ever chime in on these discussions.
