Hello Micki,

Thanks for reporting your current issue.

For your information, WebUI 2007 R2 was already discontinued years ago and we no longer provide any support on that version. Using WebUI 2007 R2 in your current environment, such as VS 2015 and Windows Server 2012 (64 bit) is not recommended since it was using an outdated technologies. It doesn't even support the latest modern browsers, e.g. IE11, Chrome 49 or higher, Firefox 44 or higher.

We have extremely revamped and modified all ASP.NET products lineup with new features, new UI and new technologies. I recalled that you currently have WebUI for ASP.NET subscription license, which will expire in this upcoming May 2016. I highly recommend you to renew your subscription immediately before it gets expired, and start using the latest WebUI 2016 with its new unified theming.

Thank you.
