For the record, the Win7 rig I am running the gadget on has no DesktopX installed.
Fresh install of Win 7 64 bit. Nothing added but one teeny tiny gadget.
Tested on several PC and config :
1 XP SP3 without DesktopX installed : Stardock Clock gadgets working OK
3 XP SP3 with 2 different versions of DesktopX, same result
1 Seven 32 bits without DesktopX installed : Stardock clock gadgets all working
The one with Seven Pro 64 bits (DesktopX 3.50) ! none of the Stardock clock gadgets coming with their (old) premium suites not working; wherever i put the Gadgets folder ...On this PC all your clock gadgets are perfectly working ... (well that's a trouble to get a terrible headache)
