Fix LibreOffice Installation Errors on Windows (MSI, 64‑bit)

This page covers quick fixes for common MSI install issues on Windows 10 and Windows 11. You can also safely re‑download the official offline installer below.

Installer: LibreOffice_26.2.2_Win_x86-64.msi • Size: —
Quick fixes
  • Restart Windows, then run the MSI as Administrator.
  • Close Microsoft Office, LibreOffice, and any app using office files.
  • Pause antivirus temporarily if it blocks installation; resume afterwards.
  • Ensure Windows Installer service is running (services.msc).
  • Free up disk space and delete any incomplete downloads, then re‑download the MSI.

“Another installation is in progress”

  • Restart Windows to clear pending installs.
  • Open Services (Win+R → services.msc), restart Windows Installer.
  • Wait for Windows Update or other installers to finish before starting LibreOffice setup.

“Error opening file for writing”

  • Close all office apps and background updaters.
  • Right‑click the MSI → Install (admin)
  • Temporarily pause antivirus if it quarantines the installer, then resume after install.

Insufficient privileges / Access is denied

  • Use an Administrator account or run from an elevated Command Prompt.
  • If on a managed PC, contact IT — Group Policy may restrict MSI installs.

Installer failed or seems corrupted

  • Delete the old file and re‑download the official MSI.
  • Check the file size appears complete (see “Size” above).
  • Avoid third‑party sources; use official mirrors only.

Rolling back changes or stuck near 100%

  • Close open applications and try again.
  • Reboot into a clean boot (only Microsoft services), then run the MSI.
  • If upgrading, uninstall previous LibreOffice first, then install fresh.
