    “Clean” Uninstall

    With the release of any new version of software upgrading should be easy, just click the new installation fill and voila, hey presto, thank you very much and enjoy the new tools. However, Autodesk Civil 3D now contains so much functionality that it relies on numerous stored settings, support files and code libraries located all over your computer that removing the previous version can be a big job. Generally, we recommend that you finish a project in the version of Civil 3D you created it in, but we also encourage you to move on to the latest version to take advantage of the latest enhancements.

    One of the most important things we suggest is that you avoid migrating the settings from your previous version into the new one without testing. The way that you configured Civil 3D 2017 may not right for the 2019 version. Occasionally when upgrading you may get errors, failure to install completely, failure to open once installed or not enough space to complete installation.

    So, what can you do? Call IT, wait a while, then have them scratch their heads and be no closer to a solution. (Hopefully not!)

    You could try uninstalling the software from the control panel, but this may not remove the programme file in its entirety. With Autodesk software it is advised to conduct a “Clean Uninstall”.

    This is done by using the prebuilt Autodesk Uninstall tool, accessed from the Start menu under the Autodesk Folder.


    The Autodesk clean uninstall tool provides a simple way to remove all the registry files and any other associated files that have been included within your install.

    You can see from the attached image all the files that a single install can contain, for example, Navisworks Manage contains ten other file installs that may be left behind if you don’t use the clean uninstall option.

    Once you have uninstalled items in this way, try your new install again and you should see that you no longer have any errors.
