Installation on a corporate network drive or C:\Program Files\ without admin elevation can trigger error 157 during netlist creation because OrCAD cannot write to the output folder.

The most significant technical leap in version 17.7 is the tight integration of the . In modern high-speed design, the schematic is no longer just a connectivity map; it is a rule repository.
