I have a user who is on Windows 8.  They have the full version of Office 2010 and they want to get their Smartermail calendar into outlook.  So I go to the smartermail web interface, go to the calendar, then under actions I choose, Add to Outlook.  I choose Outlook 2007 or Later and leave the other settings alone.  Press OK.  Then get a window that states, do you want to allow this website to open an app on your computer?  So I press Allow. 

 

Then I get a windows error:  No apps are installed to open this type of link (stssync).  My only option then is to Look for an app in the store.  I don't want that, I want to use outlook. 

 

That is it.. I am stuck, dead in the water.  Any assistance is greatly appreciated.
