Warning Message Installing Virtual Private Network or DUN

CAUSE

This behavior can occur if you use system policies, and you have enabled the Digital Signature Check policy. The warning message you receive depends on the level of security specified in the policy.

When you install a program using the Add/Remove Programs tool and the Digital Signature Check policy is enabled, Setupx.dll expects a full path statement to verify that drivers have been properly signed. When you install DUN or VPN using the Add/Remove Programs tool, Setupx.dll receives a file name rather than the full path statement, causing the warning message to appear.
