Office 365    
Office 365 is a subscription service from Microsoft and not a version of Office/Excel.

Office 365 Business and Office 365 Business Premium are suitable for VT Final Accounts.

Office 365 Business Essentials does not include a desktop version of office so is not compatible with VT Final Accounts.

VT should always be installed (or installed again) after you have installed Excel, and the VT installation program will give a warning message and will not proceed if it cannot find a suitable version of Excel.
