Logon Failure

Access denied error? Please verify the used service user account.

Access Denied

It is possible to run the DataFlex Web Application Server under a different service user account. This is commonly used to grant the Web Application Server access to a network resource.

Please verify that the user account you use has valid credentials and sufficient access rights to the DataFlex installation folder and registry keys.

The Installation might be damaged or incomplete

It could happen that there was an error during the installation of DataFlex. If the DataFlex 18.x Web Application Server still refuses to start after performing the steps above, it is recommended to reinstall DataFlex.

Note: On some systems, uninstalling DataFlex may create problems in the new installation. This happens because there could be DataFlex files that were locked during the uninstallation process.

It is common for Windows to remove those locked files after the first reboot. If DataFlex was installed before rebooting the machine, the newly installed files might be deleted, damaging the new installation.

It is recommended to reboot your machine after uninstalling DataFlex.
