msiexec /i "C:\Installers\Software1.msi" /qn
msiexec /i "C:\Installers\Software2.msi" /qn
echo Installation complete.

Explanation: A batch script that silently installs multiple software packages without user intervention.

Troubleshooting Installation Errors

In cases where installation errors occur, the /L*V option allows you to generate a log file, making it easier to diagnose the problem.

msiexec /i "C:\Path\To\Software.msi" /L*V "C:\Logs\InstallErrorLog.txt"
