WOT Community Badge for updatestar. XP, 32 bit and 64 bit editions. Simply double-click the downloaded file to pdf outlook previewer not working reg key it.
You can choose your language settings from within the program. I was excited to get the RTM of Office 2016 but dismayed that the Excel preview function did not work in Outlook 2016. Other previews were fine, like PDF and Word. Firing up Process Monitor showed the problem pretty quickly. The registry key for the Excel Preview handler is not the same as the other working handlers. This is a brilliant and simple solution, which also works for the 64-bit version of Windows 10. This fixed the problem with the previewer.
