<main> <article class="userContent"> <p><strong>Problem:</strong></p> <p>Cannot select a machine in <strong>Agent > Application Blocker</strong> page</p> <p><strong>Cause:</strong></p> <p>The machine which you are attempting to select has another agent installed that is currently using the drivers required by application blocker</p> <p><strong>Solution:</strong></p> <p>Please hover your mouse on the agent icon where you are trying to set the setting. It will give you a message like shown below</p> <p><img src="/attachments/token/KZBDPyldcd0f13Xa047FF1xaR/?name=Evaluation+Edition_20150306_13-40-29.jpg" alt="Evaluation_Edition_20150306_13-40-29.jpg" class="embedImage-img importedEmbed-img"></img></p> <p> </p> <p> </p> <ul><li>This suggests that the driver Kaseya requires for application blocking is being used by another agent on that machine.If multiple agents are installed on a machine, only one agent at a time controls the drivers required to use <strong>File Access</strong>, <strong>Network Access</strong>, <strong>Application Blocker</strong>. These functions can only be performed by the agent controlling these drivers.</li> <li>In order to verify if there is another agent on that machine or not, please either check it from <strong>Audit > Add/Remove Programs</strong> on VSA or from Task Manager > Services > Kaseya Agent Service (there should be 2 service if you have 2 kaseya agents on that machine)</li> <li> If there is no other agent installed on that machine and if you are still seeing the issue, please perform a force agent update from <strong>Agent > Update Agent</strong> page / <strong>Agent > Manage Agents > Manage button > Update Agents</strong>. Please contact Kaseya Support if this does not resolve the issue </li> </ul><p> </p> <p>Applies to: v6.2 and above.</p> </article> </main>
