What about System Requirements and Disk Space?

See System Requirements
For an estimate of disk space, add 50% to the stated Library download size e.g. a 10.8 GB download plus 5.4 GB (50%) = 16.2 GB disk space.

Why is the required disk space so large?

Logos has to store your Resources & Documents together with datasets & images for many of its features, and it builds a large Index which makes Logos’ search speed possible. A Library of 2320 books uses about 32 GB.

What can I do if I don’t have enough disk space?

Delete temporary files and unused OS files, which can take up several GB. If possible, install Logos on a “Data” partition of your disk drive, or move large collections of photographs and images to an external drive.

If that is not possible, then Logos 8+ allows you to select a smaller/minimal installation. Which means that the above 32 GB full installation only uses 15 GB with 480 books downloaded. The remaining books are still listed in Library, and can be easily downloaded.
Note that all your Datasets (c. 5 GB) + all your Documents will be in both installations.

How can I install Logos in a different folder or drive?

Where does Logos install resources?

Operating System Logos Resources Path
Windows C:\Users\username\AppData\Local\Logos\Data\random\ResourceManager\Resources Logos on Windows 7 SP1 or newer
Windows C:\Users\username\AppData\Local\Verbum\Data\random\ResourceManager\Resources Verbum on Windows 7 SP1 or newer
macOS /Users/username/Library/Application Support/Logos4/Data/random/ResourceManager/Resources Logos on OS X 10.5 Leopard or newer
macOS /Users/username/Library/Application Support/Verbum/Data/random/ResourceManager/Resources Verbum on OS X 10.6 Snow Leopard or newer

Substitute your computer user name for username
random is a randomly generated User Identity which allows multiple Logos users to login and have their own data (e.g. resources) and documents.

Windows note: to view the \AppData folder you have to turn on the “Show hidden files and folders” option under Control Panel | File Explorer Options | View.
macOS note: to view the ~/Library folder see

Why does Logos install into your username directory?

The simple answer is to avoid the need for Administrator rights (permission elevation) every time it is installed, updated or run; particularly during the frequent background updates. This is becoming common, and is what Google Chrome does, for example.

Another factor is that Logos requires a login with a unique user identity, so Logos decided it would be much easier to install in the user profile. This also supports a church (or home) computer shared by two people who WANT separate Logos accounts, profiles, settings (and resource collections).

For two separate users on the same computer you will need to install Logos in two user profiles. If you install the same Logos account in different user profiles (or different computers) it will sync settings, documents, history, etc. between those two installations.

Why doesn’t Logos work when I install it as Administrator?

Logos is designed as a per-user application, so if the installer ever needs Admin rights it will request them e.g. to install the .NET Framework or update system-wide fonts. But if you install it using “Run as administrator” you will experience problems with regular updates of the application (and will need to run Logos the same way for the update to succeed).

Is there a faster way to install Logos on another computer?

It is possible to install Logos onto another computer without downloading and/or indexing if you use an unofficial procedure to copy resources and indexes from the first installation.
For Windows, Quick Installation onto multiple computers
For macOS, Quick Installation onto Multiple Macs

Note that all procedures will save downloading your resources again, which may be a concern with large libraries or imposed “data caps” where some ISPs restrict download amounts before premium charges are applied.

How do I install Logos without The Internet?

Faithlife Corporation does not provide Logos/Verbum installers without an Internet connection.

How do I uninstall Logos?

For Windows: Use Control Panel >> Programs and Features to Uninstall, which will remove all your resources, so if you wish to avoid a subsequent large download then backup the \Resources folder before uninstalling and use Quick Installation onto multiple computers to reinstall.
For macOS, use Uninstalling Logos for Mac


General facts about indexing

The Indexer builds one main ‘Library’ Index for all your resources . Earlier versions have an additional ‘Bible’ Index for bibles and morphological resources. This means that searching a collection of books or all your resources is much faster than searching through each book individually.

When new or updated resources are added to your library they are built into a temporary Supplemental index which is then merged with the existing Index. Thus the time taken is considerably less than a full Index.

How long will Indexing take?

First time indexing or re-indexing can be a long process, depending on factors like CPU speed, RAM and the number of resources being indexed. Be prepared for it to take from 1 hour (fast desktop computer) to 1 day (tablet) for 3000 resources. You should definitely consider indexing overnight whilst you sleep! Indexing for a new/updated resource can take several minutes, but takes about the same time for a small number of non-bible resources.

What happens when books are updated or after I purchase books?

Depending on your Program Settings books will be automatically downloaded or you will receive a notification. You won’t know the content of the download and the size can be smaller than you anticipate because Logos uses “patches” for many updates. When downloading has completed the books will be copied to the resource folder and indexed.

It is no longer a requirement to restart Logos for indexing but if some of the updated books are open in your layout you will be notified to (manually) restart Logos after the other books have been indexed.

Can I see how much longer the indexing will take?

In a way you can. Once indexing has begun hover your mouse over the notification icon near the Shortcut bar and you will get an estimate of how complete it is as a percentage.

Is there a way to pause indexing?

There is an option to pause the indexing and the time is set to 4 hours.
This is done by clicking on the notification icon and selecting the link.

Indexing Tips

  • Allow first time indexing or re-indexing to complete as you cannot successfully perform a Search until it is done. You can Search during the download and indexing of new/updated resources but a message in the Search panel will state that some search results may be missing or incorrect.
  • To download and index with little (or no) interaction set both Automatically Start Downloads and Download New Books to YES in Program Settings and leave Logos running.
  • If you Cancel a download Logos will start indexing the resources it has processed. Use the Update now command to resume the download.
