Run CAD from the USB drive
ProfiCAD is a software program for drawing electrical and electronic diagrams, schematics, and other types of technical diagrams.
Unzip the zip file to your flash drive and run ProfiCAD.exe.
After the program launches you should see the initial screen. If the symbols panel is blank, set the path of the symbols library using the command F12 - Paths to the "ProfiCAD Library" folder.
If you prefer a traditional installation, proceed here.
