    The latest (and previous versions) of Fidler2setup.exe /S (for Silent) fail to install with Return Code 4444.

    If there is a log I don't know where to find it and as NSIS is used there is no logging command line switch (a good enough reason to switch I'd have thought). A windows installer version would be much better (you could look at my free MAKEMSI tool, for easy command line msi building).

    The required dot net version is installed:

    ASoft .NET Version Detector Report
    Download latest version at

    ==== FOLDERS ====

    ==== Installed .NET Frameworks ====
    .NET FW 2.0
    ==== END REPORT ====

    Any ideas? Any other ways of installing it? I don't want to manually do it, has to be automated.

    Thanks for that response. I have no control over the environment and can't install updates etc to it so I probably won't be able to use fiddler....
    The download page "" doesn't correctly list the requirements, could this be updated?
    Does the installer log anywhere? How do I know why it fails?
    I did notice that although the installer returns 4444, all the files seem to have been installed....
