Access Denied Error

Description

During the patch deployment process, the installation fail with an Access Denied error. This typically occurs when the system lacks the necessary permissions to access certain files required for the update. Common causes include interference from antivirus software.

Cause

Antivirus software interferes with Patch installation by blocking access to essential files or directories required during the process. This usually happens when the antivirus mistakenly identifies legitimate installation files as potential threats, leading to restricted access or deletion of those files. As a result, the installation may fail or encounter errors due to missing or inaccessible components.

Resolution

To resolve the issue, follow the steps below:

• Temporarily disable any antivirus (AV) software running on the affected machine (or) add an exception or exclusion for the agent folder in the antivirus settings: C:\Program Files (x86)\Patch Manager Plus\UEMS_Agent.
• Redeploy the patch via Patch Manager Plus.
• Verify the results and ensure the installation completes successfully.
