What is an INSTALLLOG file?

An INSTALLLOG file is a file created during the installation of a .NET Framework service or application. It contains a description of an assembly's installation process. INSTALLLOG files are created by the installutil.exe program.

More Information

By default, .NET Framework software uses installutil.exe to install assemblies included within the software. When installutil.exe is run against an assembly, it typically creates the following three files:

  • installutil.installlog, which contains a description of the assembly's install process
  • YourAssemblyName.installlog, which contains information specific to the install process's commit phase
  • YourAssemblyName.installstate, which contains data used to uninstall the assembly

A YourAssemblyName.installlog file is created only if a developer omits the /LogFile option from installutil.exe, or the developer includes the option along with a custom file name for the INSTALLLOG file (e.g. /LogFile=MyInstallLogFile.installlog). If a developer includes the /LogFile option without specifying a filename, a YourAssemblyName.installlog file is not created.

How to open an INSTALLLOG file
