How does Advanced Installer help in creating MSI files for penetration testing?

Advanced Installer provides a GUI to create MSI packages that comply with Windows certification. A pentester can add custom actions like launching an executable (e.g., cmd.exe) and export the MSI. When run with `msiexec /q /i test2.msi`, the payload executes silently. The tool helps avoid antivirus detection compared to default Metasploit MSI files, though logs still appear in `%TEMP%`.
