Running HOOPS Communicator Converter command in Windows error

Hi there,
I am trying to convert sample .dwg to .scs using communicator-converter in windows 11.
I have attached the error below.

I am a beginner, learning quickly from documents
Thanks in advance.

Hello @chenkangck15,

It does not look like you are supplying a complete set of parameters to converter.exe for it to complete the operation. At minimum, you must provide --input, --output_scs and --license. For the first two parameters, you must include the file format extension (.dwg, .scs), for example, your_dwg.dwg and your_dwg.scs.

Perhaps an easier approach is to use the drag-and-drop utility batch file provided in the Communicator package. More information can be found here.

Thanks,
Tino

thank you for your answer.What is confusing is that I actually dragged the dmp file to the convert_file.bat batch file in the Communicator package. Is it because my computer is not configured with some environment?

I also downloaded the Communicator package from the official website. I tried HOOPS Communicator 2025.2.0, HOOPS Communicator 2025.1.0, and HOOPS Communicator 2024.7.1. I dragged the file to quick_start/convert_file.bat, and the output was the same as above. So I wonder if I missed some steps.

If you have any ideas, please let me know. Looking forward to your reply.

Thanks again,
ChenKang

For the Web Viewer, Visual Studio C++ redistributables are required as mentioned in our docs. For converter, if the redistributables are missing, you will receive a message to the effect of VCRUNTIME141.dll is missing (which is different from the message that you are getting).

The issue might be the DWG file itself. As part of the HC package, there are various CAD files included. Can you try the drag-and-drop conversion operation for the file HotelFloorplan.dwg found in the directory HOOPS_Communicator_202X.x.0\authoring\converter\example\_data?

I attempted this but encountered same error. Here’s the error message:

Thanks for the update.

One other suggestion is to install the necessary Visual Studio C++ Redistributable. Please download and install the x64 version (vc_redist.x64.exe) found in this page.

Thanks,
Tino
