title: Using RTD with Excel 2016 on Windows 10 Does Not Refresh
body: <p>I'm trying to use RTD with Excel 2016 on Windows 10 and find that it does not refresh the values without a forced update using "Application.RTD.RefreshData" in the VBA Editor.</p>
  
  <p>I've tried several RTD servers and the problem appears common only to the Excel 2016 and Windows 10 combination.  Windows 7 and Excel 2016 works as expected.  The problem is only with Windows 10.  Using Excel 2013 and Windows 10 is OK.  The Excel 2016 has all the latest updates so it is not related to the issue experienced at the end of 2015 where a server had to be specified. This bug has been subsequently fixed by Microsoft.</p>
  
  <p>To give a simple example, taking a RTD server like that described in <a href="http://blog.learningtree.com/excel-creating-rtd-server-c/" rel="nofollow">http://blog.learningtree.com/excel-creating-rtd-server-c/</a> it will give a value in an Excel cell on first entering the formula but will not "tick" (refresh) the value automatically.  If "Application.RTD.RefreshData" is used the value updates.</p>
  
  <p>Debugging the RTD server it appears that Excel 2016 is not calling RefreshData() as it does in other OSs or Excel versions.</p>
  
  <p>I've tried this on two machines and can replicate it every time.  Can't help feeling this is a bug in Excel 2016 when run on Windows 10?</p>
