A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
MS support is working on a structural fix. in the meantime a non official workarround that worked for me (to use at your own risk) is:
• For 32-bit versions of Excel running under 32-bit versions of Windows and 64-bit versions of Excel running under 64-bit versions of Windows, the key is
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
• For 32-bit versions of Excel running under 64-bit versions of Windows, the key is
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
Either way, please create a new DWORD 32bit value under that key with a name of excel.exe and a value of 0x2af8 (or decimal 11000).
best of luck,
Cédric
