Frequently Asked Questions

Q: Where can I download Logos from?

A: You can install Logos by following the instructions here.


I still have an older version of Logos...

Q: Do I have to buy Logos?
A: We regularly provide free updates to our software, which are normally installed automatically (if not, follow the steps in this article or download the installer from logos.com/download). The free updates ensure Logos will run smoothly but won’t give you access to all the latest features that would come with a paid upgrade.

Note: This free download contains a limited number of new features, resources, and books on an "access-only" basis. This means you can access them but you do not own them permanently.

Q: Will I lose anything I already own if I update?
A: No. You won’t lose access to any of your books by updating. Each free update enhances your Logos experience by fixing bugs, improving features, supporting additional resources, or adding compatibility with new versions of MacOS or Windows. Very occasionally, to support these improvements, we may remove little-used features that no longer provide value to our users. Or we might consolidate two old features into one new one to make our software simpler and more powerful. If this happens, we’ll explain the change in the release notes for that version.


I have an older version of Windows or Mac OS X...

Q: Will Logos work on my computer?
A: Older operating systems (such as Windows XP or Vista, Mac OS X 10.15) do not support the newer software. You will need to upgrade your operating system or computer to something more current to use Logos.


Q: Can I still use an unsupported version of Logos?
A: You can still use an unsupported version of Logos, although we don’t recommend it. As the table above shows, unsupported versions of the software may not be compatible with the latest Logos books and might not work with modern Operating Systems. Due to security upgrades across the internet, versions of Logos before 7.19 will no longer be able to connect to the internet.
