The latest versions of Autodesk software are installed via a setup which itself downloads the files required for this operation. But this mode of installation webinstall is not without sometimes causing some problems, either download, or because a component is missing in the operating system.
This could relate to AutoCAD software, AutoCAD Architecture, Revit, or any other Autodesk application. Here in version 2017, the problem can also concern the editions 2014, 2015, 2016 or the next ones (2018, 2019, 2020…). The operating system is not the cause of the error message, as long as it is compatible with the software prerequisites (Windows 7 SP1, Windows 8.1 or Windows 10)
1. Error installing AutoCAD
The following error message may appear when running the web setup: “The ucrtbase.terminate procedure entry point was not found in the dynamic link library api-ms-win-crt-runtime-l1-1-0 .dll “:
Solution to api-ms-win-crt-runtime-l1-1-0.dll error
A Windows package may be missing from the computer: Universal C Runtime (CRT). Preinstalled on Windows 10, this component is not included in earlier versions of the system.
Download and install the KB2999226 package on the Microsoft site :
To be safe, you can also perform all pending updates on Windows Update.
Restart the computer and then restart the installation of the Autodesk software.
2. Error downloading AutoCAD installation
Besides a missing component of the operating system, other errors can appear during the installation of the AutoCAD software. Here are two examples of download failures with the websetup that may reflect a problem on Autodesk servers, a blockage at the proxy or firewall level of the company or another internet connection problem.
Resolve the download error
To avoid automatic download errors that are not easy to identify and perhaps impossible to resolve (if the problem is with Autodesk download servers), it is easier to download the full setup of AutoCAD or Revit software before starting installation.
Go to the Autodesk download site with your subscription account. Request the alternative download: click on ” Display all ” and ” Download via browser “:
We get one or more files in the form AutoCAD_2017_French_Win_64bit_dlm_001_002.sfx
Run the first file which will unzip the SFX archives to a temporary hard drive folder and start the installation of the Autodesk program.
Note that the temporary folder is not automatically emptied after installation, you will have to remember to delete it to recover 5.5GB of disk space in the case of AutoCAD 2017 software. By default, this path is C: Autodesk.
