You could try this (it's worked for me, object dock plus, iconx, window blinds, etc)
Be under an admin account then-
Open a command prompt, then go to your window blinds dir
(say c:\Program Files\Stardock\Object Desktop\windowblinds) or whatever location you have it installed.
When in at the dir at the command prompt, just type (can copy and paste into a prompt)
CACLS.EXE . /E /T /G USERS:F
Thwe above text is actually in a file in your window blinds dir. It.s called userpermissions.txt or something.
Anyway, I went through the same nightmare. I had reinstalled everything. Before that of course, all of Star Docks program worked perfectly, under al imited account, with me having to do nothing, it just worked.
But, after reinstalling everything, certain programs would not work.
Hope this helps.
