Acrobat Windows Registry Setting FEATURE_BROWSER_EMULATION

I need to set this registry setting with the value 11000 (0x2AF8), but after Acrobat is launched the setting is reverted back to the default value of 9999 (0x270F).  Can anyone tell me why Acrobat reverts this registry setting, and can I prevent it from doing so?

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
