The correct answer is C. Change the User Account Control (UAC) settings, because the credential prompt during installation indicates that the system is requesting administrative privileges. In Windows environments, UAC is designed to prevent unauthorized system changes by prompting for administrator approval when elevated permissions are required.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, UAC acts as a security boundary between standard user activities and system-level changes such as software installation. If a user does not have sufficient privileges, the system will request administrator credentials before proceeding.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that technicians can temporarily adjust UAC settings or provide proper elevation to allow legitimate installations. This is especially common in corporate environments where users operate with standard accounts.
The Mike Meyers / Mark Soper Lab Manual reinforces that restarting the computer or using a different browser does not change permission requirements. Contacting the software vendor is unnecessary when the issue is clearly related to local security controls.
Because the installation is blocked by privilege restrictions enforced by UAC, adjusting User Account Control settings or providing proper elevation is the correct and most efficient resolution, making C the correct answer.
