If it makes you feel any better bachbeet, none of the UIS0 skins work on my Windows 7 64-bit either.

Well, I guess "misery loves company."  The others (some here and the tech guys) are telling me they do work.  The tech people can't find a solution and insist that they still should work.  Fact is they don't.  Not on mine and apparently not on yours.  Makes me think there is an error with the new uis0 format and Win 7 64 bit.  And, I don't think Stardock is aware of this error.  They should be so that they can find a solution and fix it for the next build of WB7.  Or simply eliminate those included skins that are uis0 and maybe include some that are uis2 instead.  Forget the uis0 format.

OK, after persistent help from the techs at SD (mainly Curt) we figured it out.  To apply a uis0 skin properly, one needs to first apply the default Win7 theme.  I had to do it thru the Win7 Personalize screen.  Then, all the uis0 skins work/look as they do in the previews.  If one switches to a uis2 skin after that (I switched to C5) and then tries to apply a uis0, it will look like Windows Classic, very bland.  It seems that the uis2 skins apply Classic as an underlying theme and the uis0 skins need the standard Aero skin.  Hope this helps anyone else (e.g. Lightstar).

if you can in stall your OS on a new partion

then install Impluse then WB.

then if it works you will know something is causing it not to work on the other partion.

then you could install stuff one -by -one to see what program it is.

I just did it here cause WB's Explorer Backgournds will not work on my win 7 Home Premium 64bit

but it's now working on my Win 7 Ult. 32 bit same PC just 2 partions.

now I just have to find what is causing it not to work on 7 Home Premium 64bit..

I know it's a Pain in the ass but it should tell you what is causing it...

 note If you do, Do it load a skin that you do know that works and then one that you know that is not working and restart after EVER program

EDIT never mine I just seen your last post...

DC: Thanks for all your help.  You're a good guy.

you are welcome ...

I try some time I help most of the time it's a no go

I have 7 64bit and I find the only way to use the aero skins in windowblinds is to first enable an aero theme under the default windows personalization option. I can then click any of the aero themes in windowblinds and they work. I don't bother doing that though because I never use them.
