In order to display desktop gadgets, you must enable the User Account Control, and enable desktop items.
Hope this helps.
I was in the same quandry and found the following,
I was able to add gadgets from the microsoft web site and they would install and run but
was unable to bring up the program file folder to start already installed gadgets.
Once I had a gadget up I could access the folder through "right click/add gadgets".
Right clicking desktop and click gadgets, nothing would happen as was true
with control pannel route as well!
Spent many hours going through the tec-web and trying every suggestion to no avail.
Steps taken to access desktop gadgets
Checked and reset (where nessessary) the following
UAC -on (recomended level)
show desktop icons - on
show desktop gadgets - on
windows gadgets platform - on
%PROGRAMFILES% - no responce
control panel - no responce
event log - no reports
full disc check - volume is clean
system file checker - no integrity violations
running regedit (as adminn)
(\settings does not exist on my unit therefore could not adjust "allow elevated process")
full virus scan - none found
protected mode - tried both on and off
The last thing I have tried is:
With the desktop gadget file open, bring up task manager, click processes,
right click "sidebar.exe", click UAC Virtualization.
A pop up question comes up "do you want to change virtualization for sidebar.exe......"
click "change virtualization"
Now most if not all built-in short cuts to the file work!
So far all is well we shall see if it lasts,
Hope this helps others.
Thus far all still works after re-boots etc.
All shortcuts still work.
