Now try to install the Bing bar from the article mentioned below – Bing Bar version 7.0 is available Alternatively, you may download from the link mentioned below as well – If the steps mentioned in Method 1 does not help then you need to go to Method 2. Method 2- Since the Installer was installed successfully means that there is no fault with the Windows Installer. As mentioned earlier, you need to refer to the Bing forums for further assistance since the issue is limited only to Bing. Hope this helps!!
