Converter uses administrative shares ( C$ , ADMIN$ ) to copy its agent files. If the source machine’s Windows Firewall, Local Security Policy, or User Account Control (UAC) restricts remote administration, the driver will not be staged correctly.
You must use VMware vCenter Converter Standalone 6.2 or the newer 6.3 release (often bundled with vSphere 6.7/7.0 U1 or available via Broadcom/VMware download portals).

When this error appears, it typically halts the conversion process immediately, leaving administrators staring at a failed job log and a ticking project deadline.

This is the most common fix recommended by VMware/Broadcom support. : Go to User Accounts > Change User Account Control settings . Move the slider to Never Notify . Restart the system for changes to take effect. Via Local Security Policy (for servers): Run secpol.msc . Navigate to Local Policies > Security Options .
