Full Guide: FME Flow Troubleshooting Guide

Are you encountering issues when uninstalling FME Flow (formerly FME Server)? Please read below for some common troubleshooting tips, questions and resources.

Troubleshooting Tips

  • Make sure the Services have been turned off. You can confirm these services are not running by looking for fme tasks in the task manager.
  • If you are uninstalling FME Flow, please ensure that you have created a valid and comprehensive backup. More information is available in the documentation .
  • Log Files for FME Flow migrations (backup and restore) can be accessed in the web interface.
    Resources > core > current/old > fmeconfiguration.log
  • The uninstall process may leave behind some files and directories if there have been any post-installation configurations. It is okay to remove these files – you may consider keeping a backup of these files.
  • SSL Configuration is not included in a backup. It may be a good idea to copy the <FMEFlow_InstallationDir>/Utilites/tocmat folder for a reference to make easier SSL configuration if you are upgrading.

Common Issues

“How can I completely uninstall FME Flow? Is there anything left behind?”

After uninstalling FME Flow – for example, using the Programs and Features application – you may notice that the installation directories remain, particularly the <FMEFlow_InstallationDir> and <FMEFlow_SystemShare>. These directories may remain if they contain files that were added, modified, or shared after initial installation. After uninstalling FME Flow, it is safe to delete these directories. Please review these files in case you need to save them for a backup!

Note: The default location for <FMEFlow_SystemShare> is C:\ProgramData\Safe Software

Linux Only

On Linux, uninstalling removes the configuration of the below components but does not uninstall them. They are reconfigured when FME Flow is reinstalled. If you want to use the more current version of these components, remove them completely, and update the system packages before re-installing:

  •  The PostgreSQL FME Flow Database, if applicable
  •  The NGINX reverse proxy

In these cases, after a reinstall, you may be prompted to use port 81 instead of 80. You can however choose port 80 despite the warning and it will reconfigure the NGINX to use that or any port set.

Similarly, the Postgres database will not be removed with the Uninstall. If you choose to keep the database application and do not manually remove it, the installer will use an existing install of Postgres (as long as it has been installed from the system package), regardless of the version.
