Installation Monitor is Microsoft's Windows 2000 command-line tool that tracks changes made by Setup programs in any secondary processes they invoke, including changes to registry entries, files and .ini file entries. Installation Monitor creates an .iml file that documents all those changes, along with enough information to undo all the changes.

Perhaps the most valuable use of Installation Monitor in troubleshooting and resolution. You can use Installation Monitor to track Setup programs that are causing problems. The information it generates can also be used to replicate system settings for specific applications.

Programmatically there are three parts:

• Instaler.exe
• Showinst.exe
• Undoinst.exe
