Apache OpenOffice Calc Versions and Availability

Quick answer: Apache OpenOffice Calc is part of the free OpenOffice suite for Windows, macOS and Linux. Start at the official download page, not an unrelated download advertisement, and verify the installed release after updating.

Checked October 20, 2026. Availability and release details were checked against project documentation. This reference does not include a new native installation test or screenshot.

Current release observation

The project’s October 14, 2026 announcement identifies Apache OpenOffice 4.1.17 as a security and bugfix release for Windows, macOS and Linux. It advises users of 4.1.16 or earlier to upgrade. Recheck that announcement and the download page if you are reading this later.

The 4.1.17 release notes include improvements to document saving and SpreadsheetML formula conversion. These are specific changes, not a guarantee that every Excel workbook or macro will work identically in Calc. Test the files you actually rely on.

Platform choices and limits

Official 4.1.17 binaries cover Windows, macOS and Linux, including 32-bit and 64-bit Linux DEB/RPM packages. Match the package to the system; a Linux package is not a Windows installer.

The 4.1.x requirements list Windows 10/11 as well as older Windows releases, Linux, and Intel macOS. On Apple ARM processors the documented route uses Rosetta 2 emulation, not a native Apple Silicon build. Do not confuse a historical minimum operating-system version with a recommendation to keep an unsupported operating system online.

Some suite features require Java. That does not mean a basic Calc total requires installing an old Java runtime. The release notes contain platform-specific Java limitations; follow the requirements of the particular feature you need rather than treating Java as a universal fix.

Verify that an upgrade actually happened

For 4.1.17, the project specifies Help > About OpenOffice and this reference signature:

AOO4117m2 | Build ID 9818 | Rev. 49c05bc6fd

Compare the complete signature with the release notes. An old shortcut or a second installation can make a completed download look like a completed upgrade when the running application is still different. Record the displayed version, operating system and package source before seeking help. For later releases, use their own reference signature, not the one above.

Keep a backup before changing software used for important documents. An upgrade’s save-related fixes do not replace backups, and an existing file should not be the only test copy.

A reproducible basic check

The following is a suggested manual check with independently calculated answers. It was not executed in OpenOffice for this page.

  1. Create a blank spreadsheet and enter 12 in A1 and 18 in A2.
  2. In A3, enter =SUM(A1:A2). The expected result is 30.
  3. Replace A2 with 20; the expected result is now 32.
  4. Save the disposable workbook in the application’s native spreadsheet format, close it and reopen it. Verify the inputs and A3 formula remain intact.

If the formula appears as text, first inspect how the cell was entered and formatted. If reopening changes the result, record the file type and exact steps before trying your real workbook. A successful SUM check establishes only a tiny calculation/save workflow, not chart, macro or cross-program compatibility.
