Bhuvan3D is not compatible with IE 9 so it has to be downgraded to IE8.
You can remove IE9 and install IE8 using the following steps:
1. Close all programs.
2. Click Start, and then click Control Panel.
3. Click Uninstall a Program under the Programs category
4. In the Tasks pane, click View installed updates.
5. In the list of installed updates, double-click Windows Internet Explorer 9.
Once Internet Explorer 9 has been uninstalled from your system, the computer will require a reboot. After rebooting, your computer should now revert back to Internet Explorer 8.
