Installation Questions

1. How do I install QTCAD?

QTCAD is distributed as a downloadable package via the Nanoacademic Technologies client portal.

A license is required to run the software. A free trial license valid for 30 days is available. To request a license or for licensing inquiries, please contact us.

QTCAD is available for Windows, macOS, and Linux operating systems. For detailed installation instructions, please refer to the Installation page.

2. What should I do if I encounter the error ModuleNotFoundError: No module named 'qtcad'?

This error often occurs if the QTCAD package is not installed in the currently active Python environment, or if the environment was not properly activated before installation.

Please ensure that you have:

  • Activated your QTCAD conda environment (by running the conda activate qtcad command) prior to installing QTCAD (which is done by running the pip install . command).

  • Completed the installation steps as described on the Installation page

If you are still experiencing issues, please contact us for assistance by submitting a ticket to the Nanoacademic Customer Support Center.

For more efficient troubleshooting, we highly recommend sending us a list of your environment packages by running:

conda list > environment_packages.txt

and attaching the generated file to your support ticket.
