Question: Can SCIA Engineer work in Viewer Mode if you don't have a license to use the software?
Answer: SCIA Engineer can work in Viewer Mode if you don't have a license to use the software.
After installing SCIA Engineer: https://www.scia.net/en/scia-engineer/downloads
You can find SCIA Engineer XX.X Viewer via the Windows Home key.

There are limitations to the Viewer Mode:
- Currently, the Viewer Mode is only available for the old interface of SCIA Engineer.
- You cannot edit or calculate projects.
- If the project is saved with results, then you can view pre-calculated checks. This means that checks should already be pre-cached in the project (i.e., certain checks should have been generated earlier in non-viewer mode).
- Projects cannot be saved or exported to any file format.
