I am having problems installing the Outlook Plug-in.

I am having problems installing the Outlook Plug-in.

I am running a Windows 8.1 on a Surface Pro using Outlook 2013 through Office 365. The primary plug-in candidate Sugar Plug-in for Outlook 365 32bit 2.1.0 fails with a message "Microsoft Outlook 2010/2013 32 bit is not detected on this machine. Please confirm you are using the proper setup of plugin."

I have also attempted installing other versions, but get the same error message.  I have tried to following the "Installing the Sugar Plug-in for Outlook" to the letter including uninstalling Microsoft Visual Studio 2010 Tools for Office Runtime.  Microsoft .NET 4.0 Framework seems to be already installed.

Any advice would be gratefully received.

Regards...Stephen.
