Can Office 2019 Standard and Access LTSC 2019 Be Installed Together?
Question details
The user wants to know if Microsoft Access LTSC 2019 can be installed on a system that already has Office 2019 Standard installed.
- Product
- Microsoft Office 2019 Standard, Microsoft Access LTSC 2019
- Device & OS
- not provided
- Scenario
- Deploying multiple standalone and suite Microsoft Office products of the same release year on a single computer.
- Observed behavior
- Evaluating compatibility constraints when mixing Office suite installations that may have overlapping applications or conflicting installation technologies.
Verify that your existing Office 2019 Standard installation uses the Click-to-Run deployment method rather than a Windows Installer (MSI), as mixing the two technologies for products of the same year will cause an installation failure.
Deploy Both Applications Using Click-to-Run (C2R)
Install Access LTSC 2019 alongside Office 2019 Standard by ensuring both products utilize the identical Click-to-Run deployment technology.
Microsoft enforces strict deployment rules regarding overlapping Office installations. Generally, you cannot install two products of the same version year if they use conflicting installation technologies (like MSI and Click-to-Run). However, since both Access LTSC 2019 and modern deployments of Office 2019 Standard utilize the Click-to-Run technology, they can coexist seamlessly.
Open any existing Office 2019 application (like Word), navigate to File > Account, and look under the 'About' section to confirm that 'Click-to-Run' is listed.
Download the Microsoft Office Deployment Tool (ODT) and configure your XML file to target the Access LTSC 2019 Click-to-Run installation.
Execute the ODT setup command in the Command Prompt to deploy Access LTSC 2019. The system will detect the compatible Click-to-Run framework and allow the installation to proceed alongside Office 2019 Standard.
Avoid Deployment Conflicts with WPS Office
Skip the complex Office Deployment Tool configurations and Click-to-Run vs. MSI restrictions. WPS Office provides a complete, lightweight, all-in-one productivity suite that requires zero advanced deployment planning while offering exceptional compatibility with Microsoft formats.
- 1. Download the Installer: Visit the official WPS Office website and click the Free Download button to get the unified setup file.
- 2. Install WPS Office: Run the downloaded executable. The lightweight installation takes only a few moments and avoids complex deployment scripts.
- 3. Start Creating: Open WPS Office to immediately access Writer, Spreadsheet, Presentation, and PDF tools in one single unified application.
Frequently Asked Questions
Can I mix MSI and Click-to-Run Office installations on the same computer?
No. Microsoft generally does not support installing an MSI (Windows Installer) version of Office alongside a Click-to-Run version of the same release year. Both products must share the same underlying installation technology.
Does Microsoft Access LTSC 2021 use MSI or Click-to-Run?
Access LTSC 2021 exclusively uses Click-to-Run as its installation technology. Microsoft transitioned away from Windows Installer (MSI) for Office LTSC releases starting with the 2019 versions.
What happens if I attempt to install conflicting Office versions?
The Office installer will detect the conflict and display an error message, halting the installation. It will explicitly state that you cannot mix installation technologies or install incompatible overlapping applications.
