On Microsoft Windows operating systems, the Windows Installer package is used to install, repair, reinstall, or uninstall programs. Most Microsoft and non-Microsoft software uses the installer to perform setup tasks, such as installing, repairing, and uninstalling software.
The increasing use of this utility has also led to some bugs. The most common problems users face are: ‘Windows Setup Service could not be accessed’, ‘Error 1706: Setup cannot find the necessary files’, ‘Error 1720: There is a problem with this installation package. A script required for this installation to complete could not be executed.’

1. Reinstall the installer
2. Fix registry keys
3. Modify the image path in the registry
4. Let RPC interact with your desktop
