Office 365 ProPlus Excel preview fails

So the Office 365 ProPlus Click to run has been upgraded to match the Office 2016 version. But unfortunately it has come with a small bug when accessing the preview for Excel.

I’m sure this will be updated soon and when running click to run enabled updates and I hope You all do it will be fixed. But in the meantime You can apply this quick fix.

The error shows up like this when trying to preview Excel spreadsheets:

Go into to the registry and go to the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftOfficeClickToRunREGISTRYMACHINESoftwareMicrosoftWindowsCurrentVersionPreviewHandlers

There You can see that the Excel previewer has a slightly different value.

Wrong regkey

Delete the REG_EXPAND_SZ key and create a new String value (REG_SZ)

Name: {00020827-0000-0000-C000-000000000046}

Value: Microsoft Excel Previewer


Right key





Restart Outlook and Excel preview will work!
