Calendar Gadget in Windows Sidebar Is Blank With Orange Background

The Calendar gadget in the Windows Sidebar may display blank content, showing only the plain orange background. Also, the Stocks Gadget may not show up when you add it to the Sidebar. This problem is usually caused by a missing scripting run-time registration.

Registering VBScript.DLL

Registering the vbscript.dll file from an admin Command Prompt fixes the problem. Follow these steps:
1. Open an Admin Command Prompt window. To do so, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as Administrator.
2. Type the following command and press ENTER:

regsvr32.exe vbscript.dll

You should see the following message after running the command:
DllRegisterServer in vbscript.dll succeeded.

3. Restart Windows and see if the Calendar and Stocks Gadgets render correctly.
