Freaky. I know.
When I right-click the desktop and click "Gadgets," it returns me this obtuse message:
If I go directly to the EXE in Program Files (x86), I get this surprising error:
Likewise, the EXE in Program Files:
I don't know what could have caused this at all. I had a Dell technician control my computer yesterday; I wasn't terribly attentive. I particularly remember he deleted the contents of the Temp folder.
I tried sfc /scannow which found lots of errors in the the Sidebar and Gadgets from my view of the CBS.log; I tried resetting whatever Regsvr32 resets of the Sidebar.exe files; I also tried disabling/re-enabling "Windows Gadget Platform" in the Windows Features Turn On-Turn Off section = nothing. Same errors.
Any ideas what could be causing this confusing problem?
