I have set the DWORD value to 11001 (0x2AF9) 
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION\myching.exe

however the JavaScript errors are still occurring. I can confirm the browser version is 11 by navigating to www.whatismybrowser.com in my application.

I have also tried the value 11000


BTW A better source of information for setting browser version is this URL (which distinguishes 32 bit and 64 bit programs)
