- Product
- Microsoft Office LTSC 2024, Microsoft Publisher LTSC 2021
- Device & OS
- not provided
- Scenario
- Attempting to install and run two different LTSC versions of Microsoft Office products (2024 and 2021) on a single machine.
- Observed behavior
- Seeking clarification on potential installation conflicts, licensing errors, or component incompatibilities between different Microsoft Office LTSC versions.
Before attempting to install or modify multiple versions of Microsoft Office, verify your current system requirements and consult your IT administrator regarding enterprise deployment rules.
Avoid Mixing Different Office LTSC Versions
Installing Office LTSC Professional Plus 2024 alongside Publisher LTSC 2021 is highly discouraged due to shared component conflicts. It is better to rely on a single, unified Office release.
Microsoft generally does not support installing different versions of its enterprise LTSC suites on the same device. Mixing versions can lead to registry conflicts, licensing activation failures, and shared application components overwriting one another.
Determine whether you strictly require the 2024 version of Office LTSC, or if an older, complete suite would suffice for your workflow.
Uninstall the mixed versions and install the unified Office LTSC 2021 package, which natively includes Microsoft Publisher alongside Word, Excel, and PowerPoint without any version conflicts.
If you are upgrading from an older setup, consider retaining Office 2019, which is stable and also includes Publisher built-in.
If a mixed deployment is absolutely necessary for your enterprise, consult Microsoft Office Management support documentation to check for any updated, specific Click-to-Run compatibility matrices.

Frequently Asked Questions
Why is it not recommended to install Office LTSC 2024 and Publisher 2021 together?
Mixing different major release years of Microsoft Office LTSC products can cause Click-to-Run installation conflicts, shared registry errors, and issues with the Office licensing service on the same operating system.
Does Office LTSC 2024 include Microsoft Publisher?
No, Microsoft is actively retiring Publisher. Newer versions of Office, including LTSC 2024, do not include Publisher, which is why users often attempt to install older standalone versions.
What is the best alternative if I need Publisher alongside my other Office apps?
The most stable solution is to install the complete Office LTSC 2021 or Office 2019 suite, as both of these natively include Microsoft Publisher and ensure 100% component compatibility.
