Open-Source Office Software for Business: OpenOffice, LibreOffice and Deployment Guide

Both suites descend from OpenOffice.org, the open-source release of StarOffice. In 2010 most of the community forked the code as LibreOffice under The Document Foundation. The original code base passed to the Apache Software Foundation in 2011 and became Apache OpenOffice.

The two projects have since diverged. Apache OpenOffice publishes occasional maintenance releases, mostly security and bug fixes, with few new features. LibreOffice follows a regular release schedule, with a feature branch and a more conservative branch for production use. Its file-format filters, interface and packaging have been revised continuously for more than a decade.

For a new deployment, choose LibreOffice and run the release line its project marks for conservative or enterprise use. Keep Apache OpenOffice where an existing installation, extension or documented procedure depends on it, and plan its replacement on your own schedule rather than in response to a security notice.

The administrative concepts in this guide apply to both. Where they differ, the difference is noted.

The comparison is less about features than about where documents live and how people work on them together.

An open-source suite suits organizations that edit documents locally, store them on their own servers, and value open formats. A cloud suite suits teams that co-author constantly. Many organizations run both: a cloud suite for collaboration, and LibreOffice for kiosks, shared workstations, contractors, or roles that only read and lightly edit files.

LibreOffice and OpenOffice save in OpenDocument Format (ODF: .odt, .ods, .odp), an ISO standard. Microsoft Office uses Office Open XML (OOXML: .docx, .xlsx, .pptx), also standardized, though Microsoft's applications write a broader version than the strict standard. Both suites can read and write the other's formats. Fidelity depends on the document.

• Decide on one default format per workflow. If most files go to outside parties using Microsoft Office, save in OOXML by default. If documents stay internal or are archived, ODF is the more durable choice.
• Install the fonts your documents use. Many layout changes after conversion are font substitutions. Microsoft's Calibri and Cambria have metric-compatible open alternatives, Carlito and Caladea.
• Use styles rather than manual formatting. Documents built on paragraph and page styles convert far more reliably.
• Test the difficult cases: tracked changes, complex tables, text boxes anchored to pages, pivot tables, conditional formatting, and SmartArt.
• Send PDF when the recipient only needs to read the document.
• Keep a small regression set of your organization's real documents and open it in each new release before rolling that release out.

Windows deployment follows a familiar pattern: obtain an MSI package, decide which properties to set, assign it centrally, then manage configuration through policy.

The MSI package

LibreOffice publishes a Windows MSI directly. Apache OpenOffice ships an executable that unpacks an MSI; running it with the administrative switch extracts the files to a network share for distribution.

setup.exe /a

Silent install switches

A typical silent, per-machine LibreOffice install:

msiexec /i LibreOffice_x64.msi /qn /norestart ALLUSERS=1 ^
  CREATEDESKTOPLINK=0 REGISTER_ALL_MSO_TYPES=1 ^
  ISCHECKFORPRODUCTUPDATES=0 QUICKSTART=0 ^
  RebootYesNo=No UI_LANGS=en_US /l*v C:\Temp\libreoffice-install.log

• ALLUSERS=1 installs for every user on the machine.
• REGISTER_ALL_MSO_TYPES=1 associates Microsoft Office file types with LibreOffice. Use REGISTER_NO_MSO_TYPES=1 where Microsoft Office stays installed alongside it.
• ISCHECKFORPRODUCTUPDATES=0 turns off the built-in update check, so updates arrive through your own process.
• QUICKSTART=0 leaves the system tray preloader off.
• Feature selection uses the standard ADDLOCAL and REMOVE properties; inspect the MSI's feature table to get exact names for your version.

Always write a verbose log during pilot rollouts. It is the fastest way to read a failed install.

Group Policy assignment

Copy the MSI to a share readable by computer accounts, then create a Group Policy Object under Computer Configuration → Policies → Software Settings → Software Installation and assign the package. Group Policy software installation cannot pass command-line properties directly, so apply them through a transform (.mst) created with an MSI editor such as Orca. Alternatively, run the msiexec command as a computer startup script or deploy it through Configuration Manager, Intune or another endpoint tool.

Remove an older version before assigning a new one if the packages do not upgrade cleanly, and test the change on one organizational unit first.

Registry settings and administrative templates

LibreOffice reads policy settings from the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice (and the matching user hive). Each key mirrors a path in LibreOffice's configuration, with a value and a flag that can mark the setting final so users cannot change it. Administrative templates (ADMX/ADML) expose these keys as Group Policy settings; add them to your central store and edit them in the Group Policy Management Console.

The alternative, which also works for Apache OpenOffice, is a configuration extension (.oxt) or a shared configuration layer containing .xcu files, installed with the suite. This is how settings were centrally managed before registry policies existed.

Default file formats

Users set this under Tools → Options → Load/Save → General → "Always save as". Centrally, the same setting lives in the configuration path for each application's default filter, for example the Writer filter set to "MS Word 2007 XML" to save .docx by default. Pair it with turning off the warning shown when saving in a non-ODF format, or users will see it on every save.

Update checks

Turn off the update check at install with the MSI property above, or remove the online update feature. Then own the update cycle: track the project's release announcements, test against your document regression set, and redeploy.

The Java dependency

Writer, Calc and Impress do not need Java. A Java runtime is used by some components: certain database features in Base, some wizards, and Java-based extensions. Recent LibreOffice versions use an embedded Firebird database by default, which removes the most common reason to install Java. If none of your workflows need it, leave Java off the image and disable Java in the suite's advanced options.

• Inventory macros. Find every workbook and document with VBA. LibreOffice can run part of VBA, but not all of it. Mark each macro rewrite, retire, or keep on Microsoft Office.
• Inventory integrations. Add-ins, mail merge sources, document management connectors and line-of-business systems that call Office directly.
• Rebuild templates. Recreate letterheads, forms and slide masters as native templates with proper styles. Distribute them through a shared template path set by policy.
• Install fonts. Include brand fonts and metric-compatible substitutes in the image.
• Choose default formats. Document which format each team saves in, and why.
• Pilot with real work. Pick a group that exchanges files with outsiders and collect concrete failures, not general impressions.
• Train on differences. Short sessions on styles, the sidebar, export to PDF, and where familiar commands moved. Publish an internal page of known issues.
• Keep an exception path. Some roles will still need Microsoft Office. Decide who approves that, in writing.

Neither project sells support directly. LibreOffice has a list of certified developers and companies offering long-term support builds and contracts; community help is available through its forums, mailing lists and bug tracker. Apache OpenOffice relies on community forums and mailing lists.

Treat the office suite like any other application that opens untrusted files. Subscribe to each project's security advisories, set a patch window, and keep macro security at a level that blocks unsigned macros from outside sources. Disable macro execution entirely where no workflow needs it. An unmaintained installation is a larger risk than any feature gap.

An office suite stores and edits documents. AI tools draft, summarize, translate and restructure them. Keep the two roles distinct. Documents remain in the suite and in open formats on systems you control; an AI tool is brought in for a defined task and checked before its output is saved.

Before connecting any AI tool to business documents, check what it stores, whether inputs are used for training, who owns the output, and how you would leave. How to Evaluate Free and AI Software Tools sets out that review in detail.

Noemic works the same way. The layer connects focused tools — Sense → Decide → Act → Learn — rather than absorbing every task into one application. Independent Software describes why focused tools with a clear contract remain the dependable choice.

Is Apache OpenOffice still maintained?

Apache OpenOffice still publishes occasional maintenance releases under the Apache Software Foundation, but development is slow and new features are rare. LibreOffice receives regular feature and security releases and is the more active project.

Should a business choose OpenOffice or LibreOffice?

For a new deployment, LibreOffice is usually the practical choice because of its release cadence, broader file-format work, and MSI packaging. OpenOffice remains a reasonable choice only where an existing installation, extension or procedure depends on it.

Can LibreOffice open and save Microsoft Office files?

Yes. LibreOffice opens and saves .docx, .xlsx and .pptx. Simple documents round-trip well; complex layouts, embedded objects, advanced charts and VBA macros need testing before relying on them.

How do I install LibreOffice silently across many computers?

Use the official Windows MSI with msiexec, for example: msiexec /i LibreOffice.msi /qn ALLUSERS=1 CREATEDESKTOPLINK=0 ISCHECKFORPRODUCTUPDATES=0. Assign the package through Group Policy software installation, a startup script, or an endpoint management tool.

Can LibreOffice be managed with Group Policy?

Yes. Configuration can be locked through registry policy keys under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice, which administrative templates expose as Group Policy settings. Settings can also be distributed as configuration extensions.

Does LibreOffice need Java?

No, not for writing, spreadsheets or presentations. A Java runtime is only needed for certain components, such as some database features in Base, some wizards and Java-based extensions.

Will Excel macros work in LibreOffice?

Some will. LibreOffice can run a subset of VBA code, but compatibility is partial. Inventory macros before migration and decide whether each is rewritten, retired or kept on a Microsoft Office installation.

Where do AI writing tools fit with an open-source office suite?

As separate, checked tools for drafting and summarizing. The suite remains the place documents are stored and edited in open formats; any AI tool should be evaluated for data handling, output rights and export before it touches business documents.
