  • Both Deloria Online and it's installer package are written in legacy coding languages (Visual Studio and Visual Studio Installer) which some anti-virus software can cause problems when installing. I have gone through the game client, launcher and updater to reduce these messages as much as possible, to most cases none. I am also happy to report that in doing so, stand-alone installation is now available as well. You can simply download the latest launcher file from the website, and when executed, it will know its a clean install and do the rest. You will just need to know how to register a couple .dll files (if needed).

    If you are unfamiliar with registering .dll files or want the easier/faster route, I would recommend the Microsoft Installer. If you plan on using multiple accounts on the same machine, I would recommend the stand-alone installtion method.         
  • You should NOT have to run any components of the game in admin mode, or you may get a 'DelDownload' error. Deloria Online has 4 executables that need access to the internet, so if you have any issues you may want to make sure these components are added to your firewall safe list.

  • It is HIGHLY RECOMMENDED that you use the default install folder when using the Microsoft Installer. Do not use folders that require additional permissions.
    Default on most newer Windows OS: C:\Users\<account>\AppData\Roaming\Deloria Online
