# Patch Installation Failure

## Problem

You are trying to install patches on your network computers. However, the installation fails with one of the following error messages:

- Error Code:-2145124343
- Another installation is already in progress. Complete that installation before proceeding with this install.
- Another conflicting operation was in progress. Some operations such as installation cannot be performed twice simultaneously.
- The process cannot access the file because it is being used by another process.

## Cause

The possible reason could be either the user has initiated another installation manually or Windows Update might be installing some other updates.

## Resolution

- We recommend you retry the deployment after some time.
- If the above resolution doesn't work, then restart the system and retry the deployment.
- If restarting the system doesn't work too, then try running our [Component store cleanup patch](https://www.manageengine.com/patch-management/knowledge-base/troubleshooting-errors-in-windows-updates.html) and retry the deployment.
- If you get the "Installation failed" message again, even after following the above-mentioned resolutions, please [Contact Support](mailto:patchmanagerplus-support@manageengine.com) with the agent log files for further assistance.
