Upgrade to Bing Ads Editor version 10.7 before March 31, 2015
28 February 2015
Starting March 31, 2015, we will stop supporting Bing Ads Editor versions 10.4 and older. If you are using these versions, you can continue to access your account and make updates locally using these older versions, but you will not be able to download or upload your changes.
Install the latest version (10.7) as soon as possible to ensure that you can manage your campaigns without any interruptions. You can upgrade to version 10.7 either through the update prompt in Bing Ads Editor or by downloading it from the Bing Ads Editor download page. You can view the release notes for the list of features added to this version.
If you’re not sure of which version you are currently using, go to the Help menu and select About Bing Ads Editor.
