Windows Installer debug option

by Per Hansen


This article describes how to create a debug log for a problematic Windows MSI installation package. This option should only be used in cases where the install of your Aspera product produces and error in the install process, and it is not obvious what is causing the installation problem.


  • Product: Any
  • Operating System: Windows


The program msiexec has a debug feature, which allows you to save an installation log file. The syntax is:

c:\> msiexec /i [Aspera MSI file] /l*v install.log

Please include the install.log file when you contact the Aspera Support team with an installer issue.
