If you have a 64-bit operating system and you have ever tried to install a Windows Gadget implemented with Silverlight of Flash, you will quickly realize that the gadget will not run. It turns out that the issue lies in the fact that there is not a 64-bit version of either Silverlight or Flash but the default Windows Sidebar application that loads on start up is a 64-bit application. Thus, the gadget and the Sidebar won’t play nicely together. To fix this issue, all you need to do is have the 32-bit version of Windows Sidebar startup with Windows loads. To do this follow the instructions below:
Windows Vista
- Click the Start orb.
- Click All Programs.
- Right click on the Startup folder and click Open or Explore.
- In the window that appears, right click and select New -> Shortcut.
- In the Create Shortcut window, copy and paste the following text, including the quotes, into the Location text box: “C:\Program Files (x86)\Windows Sidebar\sidebar.exe”
- Click Next.
- Click Finish.
Windows 7
- Click the Start orb.
- Type regedit and press enter.
- Navigate to the following registry entry: HKEY_CLASSES_ROOT\DesktopBackground\Shell
- Right click on the Gadgets registry folder and click Permissions…
- In the permissions window, click on the Advanced button.
- Click on the Owner tab.
- Find your login in the Change owner to list view and select it.
- Click Ok.
- In the Permissions for Gadget window, click the Add… button.
- Enter your login name for the computer and click OK.
- Back in the Permissions for Gadget window, make sure your login name is selected in the Group or user names list and check the Allow check box for the Full Control permission.
- Click Ok.
- Repeat steps 4 through 12 for the HKEY_CLASSES_ROOT\DesktopBackground\Shell\Gadget\command registry folder.
- Double click the following registry keys in the HKEY_CLASSES_ROOT\DesktopBackground\Shell\Gadget registry folder and change the Value data field to the specified value:
Icon: C:\Program Files (x86)\Windows Sidebar\sidebar.exe,-100
MUIVerb: @%ProgramFiles86%\Windows Sidebar\sidebar.exe,-11100
- Double click the following registry keys in the HKEY_CLASSES_ROOT\DesktopBackground\Shell\Gadget\command registry folder and change the Value data field to the specified value:
(Default): C:\Program Files (x86)\Windows Sidebar\sidebar.exe /showGadgets
- Close the registry and restart your computer.
This should make the 32-bit version of Windows Sidebar start when you right click your desktop and select Gadgets and thus allow Silverlight and Flash gadgets to work correctly.
