think-cell supports Microsoft Office 2016 as well as Microsoft Office 365 with the "fully installed Office applications". Note that Office 365 Business Essentials and Office 365 Enterprise E1 do not include the "fully installed Office applications" and therefore cannot support Office COM Add-ins like think-cell.
Microsoft Office 2016 is on a technical level very similar to the Office 365 "fully installed Office applications". Everything below regarding Office 365 updates applies to Office 2016 installations if they receive feature updates.
To check if your Office installation receives feature updates, open any Office application and go to File → Account. If Update Options is available, you receive feature updates. Here you can also see the update channel through which you receive updates.
Office 365 requires the latest think-cell version, which is also compatible with older Microsoft Windows and Office versions, including 32-bit and 64-bit versions. It is therefore recommended to install the latest think-cell version regardless of which Windows or Office version you use. You can get the latest think-cell version from our download web page.
Office 365 ProPlus defaults to the Deferred Channel, where updates are released with some delay. This is the update channel recommended by Microsoft if you use Office add-ins. For details please consult Microsoft's documentation for IT administrators, Overview of update channels for Office 365 ProPlus.
Please consult with your Microsoft Office support contact if you are in doubt whether your Office 365 plan offers the Deferred Channel.
These plans default to Microsoft's updates from the Current Channel. For details please consult Microsoft's documentation for IT administrators, Overview of update channels for Office 365 ProPlus. The Current Channel is expected to get updates every month and receives the newest Office features right away.
Due to the sometimes considerable changes Microsoft makes in the Current Channel it is typically required that your think-cell installation is up to date. If you use the Current Channel with automatic updates we therefore strongly recommend that you also leave think-cell's automatic updates and online quality assurance enabled, to allow us to provide a compatible version to you.
By joining Microsoft's optional Office Insider or First Release programs, you will continuously receive Office updates in advance. A compatible think-cell version may not be immediately available. This channel should only be used for testing and if you do not require functional Office add-ins at all times. For productive work we recommend to stay in the regular Office update channels, as explained above.
If you have any further questions regarding the compatibility of think-cell with Office 365 and Office 2016 please contact our support team.
