Thanks for contacting us. It looks like you don't have the P-CAD importer installed in your Altium Designer. If you're using Altium version 13.0 or older, you can download this plugin to add the PCAD importer: https://designcontent.live.altium.com/PluginDetail/Importer_PCADASCII
If your version is 14.0+, you can install this plugin in the 'Extensions & Updates' section in Altium Designer
When you go to File > Import Wizard > Next, you'll see the 'Get More Importers...' link in the lower left corner.
Once you click on it, it'll take you to the Extensions & Updates section. Click on 'configure' near the top right. Scroll down to Importers/Exporters section and make sure P-CAD is checked, scroll to the top and click Apply.
Now the P-CAD option should appear in the Import Wizard.
Hope that helps but let us know if you are still having trouble and we’re happy to help.
