This article will cover solutions to known issues regarding the installation and start-up of Archicad 26. You'll find several specific and detailed issues that are independent of the version you have. You'll also find the reason why these problems might be happening and how to solve them.
Archicad, additional accessories (add-ons, BIM content, libraries, and objects) and product updates, etc. can be downloaded from Graphisoft’s Downloads page.
A step by step guide on how to install Archicad 26 with a single license can be found here and another one about network installation for BIM managers is here. All other installation solutions, such as unattended install of Archicad and updates, are available on this site.
If you have already installed Archicad and want to add new features, or you need to repair Archicad, the information detailed on this site can help.
Archicad 26 is not compatible with Windows 8.1 and earlier versions; it is also not compatible with macOS 10.15 and earlier versions. Customers may experience crashes at start-up when using these operating system versions, and the installation on them will not be possible in the future.
Firewall or Antivirus software alerts during installation or use
Some functions of Archicad (e.g., BIMx Hyper-model publishing, BIMcloud functions, Check for Updates, Emergency Licensing) require network access, which is why access must be granted for incoming and outgoing connections through a firewall. For full functionality and to avoid issues, allow Archicad to communicate on the network. All Archicad network traffic is limited to essential communication with Graphisoft services in accordance with the End User License Agreement.
Antivirus programs usually block access to folders in the user’s home folder for security reasons. Archicad creates BIMx configurations and log files in the Documents folder and this action may potentially be blocked. By allowing Archicad to access this folder, the BIMx related files are safe.
'The specified directory is an Archicad directory' error message during install
Archicad cannot be installed into a directory if any parent folder contains Archicad.exe or Archicad.app; this error message may be seen after selecting the installation path. Choose another folder to install Archicad or move the file that prevents the installation to another location.
'The operating system on this computer is out-of-date' error message during install
When this error message appears, the computer may not meet the system requirements or the latest operating system updates have not been installed. Update or upgrade your operating system to meet the minimum requirements.
The message can also be due to permission restrictions applied to the given computer that prevents the Archicad installer from running executable files in temporary folders. These are used to check the installed system components and install them if needed. Consult your IT or system administrator to lift restrictions.
Finally, and rarely, third party installers used by Archicad and other applications also can be damaged or corrupted, which could lead to this error message. The error message appears if Archicad cannot repair these packages (the name of the problematic software can be seen in the installer dialog under the error message). Repair or reinstall the given package from this site.
'The code execution cannot proceed because .dll was not found' error message during startup on Windows
Archicad has some prerequisites that should be installed to run correctly. These are a part of the Archicad package and installed with it if needed. But if one of them has been uninstalled or damaged, it can prevent Archicad from running or some of its parts to function.
Most known .dll files that are usually mentioned in the error messages are libmmd.dll, VCRUNTIME140.dll and MSVCP140.dll. The first is required by CineRender and implies issues with Intel C++ Compilers Redistributable Library. Others are needed for Archicad itself and means that some of the Visual C++ redistributable packages are missing or corrupted.
These kinds of issues can be eliminated by repairing Archicad or installing the prerequisites from this site.
