Installation Failed - No Port was Available

Comments

  • Im trying to install Decisions on a local server. When it gets to the end and tries to start the service, I receive the following error: [b]Error starting Service Host ManagerSystem.Exception: No port was available from 4502 to 4534[/b]
    Both IIS and the .NET Framework have been installed.
    Ive noticed that the database gets created, but there arent any tables in the database.

  • [color=rgb(34, 34, 34)][font=Arial, Helvetica, sans-serif]We have seen this error message [/font][/color][color=#222222]when Decisions cannot connect correctly to the database, and usually not related to ports.
    [/color][color=rgb(34, 34, 34)][font=Arial, Helvetica, sans-serif]We are currently working to make this error message provide more accurate information, which we aim to release to a version after 5.11+ or 6.1+.
    [/font][/color]
    [color=#222222]In the meantime, theres can be a few possible causes for this.
    [/color]
    [color=#222222]One solution may be to confirm that the SQL server login that Decisions is using to install against the database has [b]Sysadmin [/b]privilege.

    Weve also seen this issue when the disk for the SQL logs gets too full.
    You can check if a lot of these errors are being logged via the [b]Windows Event Viewer.[/b]
    To do this search for "Event Viewer" in Windows. Click Application under "Windows Logs".
    This may require that you shrink the SQL log file and attempt re-install.

    Another possible solution is to clean uninstall Decisions and re-install. This requires that you:
    1. Run the installer and clicking "Remove" to uninstall.
    2. Delete the database from your SQL server named "Decisions" (assuming you did not rename this). When deleting this, it may throw an error/warning and that wont allow you to delete. If you are deleting via [b]SQL Server Management Studio, [/b]then make sure you tick the "Close existing connections" checkbox at the bottom of the "Delete Object" window.
    3. Run the installer again to install Decisions.[/color]
