Installation

Windows Linux Mac

Download the installer for Windows, Linux and MacOS from Releases.

Note for MacOS users

Changes to the security model used in the latest versions of MacOS 11 (Big Sur), MacOS 12 (Monterey), and MacOS 13 (Ventura) mean that the operating system will show an error message ('"FIX Log Viewer" is damaged and can’t be opened. You should move it to the Bin.') when trying to start the application. To work around this, run the following command on the downloaded dmg file in a terminal before installing:

sudo xattr -d com.apple.quarantine FIX.Log.Viewer-<version>_<arch>.dmg

Alternatively download the app from command line with wget or curl instead of from a web browser. The web browser will flag .dmg file as suspicious if it does not have the correct signature. This flag is removed with the above xattr command.

I you still see the error message manually remove the app and install it again.
