Is there any way to enforce Windows 7 to run 32-bit sidebar.exe instead of 64-bit?

Why?, do you have some gadgets that are only 32bit? – Moab Mar 3 '11 at 16:49
Not that anyone has to explain or justify any question they ever ask on any stack exchange site ever - but i am curious why. – Ian Boyd Nov 10 '11 at 14:00
When we needed this to happen it was because one of our gadgets had a Silverlight control in it, and Silverlight (pre version 5) is 32 bit only – Matthew Steeples Nov 10 '11 at 14:42
Counter to this question, I would rather find out how to force the 64-bit version to run. I just noticed that on a 64-bit laptop, the 32-bit version of the sidebar is running instead of the 64-bit version. I can’t recall how it was set to autorun, but I don’t think it was by manually adding the startup entry; it was probably through an official mechanism like an autorun check-box or something. Curious. – Synetech Nov 28 '13 at 3:50

You can use regedit to edit the following registry key:

Item name : SideBar

and change the value of SideBar to this:

"C:\Program Files (x86)\Windows Sidebar\sidebar.exe" /autoRun

(The only change is loading sidebar.exe from c:\program files (x86)\instead of c:\program files\)
