Orcap-15030: The PSpice COM Wrapper error has occured.

There cold be a number of reasons but if it happening only for one project then it is likely that OrCAD project got messed up. For example - you may have deleted some files manually from the disk that are still being looked for by software

Make sure you have the latest 16.6 ISR software.

Make sure that issue is only for specific project. If yes - create a new project and copy over the schematics to it.

If you are unable to resolve it after copy - I would recommend calling in at Cadence technical support.
