Issue Description
I have a Solo license of Archicad installed on my computer. Why is Archicad starting in Demo Mode?
Solution
If you have successfully downloaded or assigned the Archicad license but it still starts in Demo Mode, ensure that you have downloaded and installed the correct version of Archicad.
A Solo license key requires the Solo Archicad version to run. To check the Archicad version, Go to Help > About Archicad.
To download Archicad Solo, go to Graphisoft Downloads page. Click on the “Legacy versions and other product types” to explore more download options then select Solo version (considering your OS).
