## Problems in Creating Endpoint Central Agent / Distribution Server Agent

### Problem

You are trying to install / upgrade "Endpoint Central Agent" and you get an error message as "Agent MSI Creation Failed".

### Cause

This error will occur if the antivirus solution in your computer blocks the agent creation or agent upgradation.

### Resolution

You need to ensure that the Endpoint Central folder is added to the exception list, so that your antivirus solution will not block the agent creation or upgradation. You can retry the agent creation. To know about adding a folder to the exception list, refer to this:
