Issue description  

While installing the ADAudit Plus agent on a target machine, you may encounter the following error:

Error code: 0x652
Error message: Another installation is already in progress

This prevents the agent installation from proceeding and typically relates to MSI-based installer conflicts.

Prerequisites  

• Local or administrative access to the target machine.

• Access to the Command Prompt with elevated privileges.

Possible causes  

• An existing installation or update is already running on the system using the Windows Installer (MSI) service.

• A previous MSI installation is stuck in progress due to a system or application issue.

Resolution  

Option 1: Wait for the current installation to complete  

• If another installer is currently running (e.g., Windows Updates, application installs), wait for it to finish.

• Retry the agent installation through the ADAudit Plus console once the process completes.

Option 2: Terminate stuck MSI processes manually  

If no known installation is running, you can manually terminate MSI processes to resolve the conflict.

Steps:  

1. Open the Command Prompt as an administrator.

2. Run the following command:

1. taskkill /im msiexec.exe /f

3. This will forcefully terminate any active MSI installations.

Use this command with caution. If another legitimate installation is running, this will interrupt it.

4. After executing the command, retry the agent installation from the Manage Agent page in ADAudit Plus.
