Windows Installer Error Fix

Operation System: Windows 7 32-bit

Problem:
Even though my current account is an administrator, when I try to install certain programs, Windows Installer Error Message says “This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package.”

Solution:
Use the (hidden) administrator account to install the program.
