Looking at your package.ini it does look correct. Can you try a path on C drive? This will verify if it is a general issue or if it is related to the mapped drive path..
Another test is to activate cmd.exe with below settings:
[cmd.exe]
Source=%SystemSystem%\cmd.exe
Shortcut=PriceRetrievalTool.exe
WorkingDirectory=N:\WPSRAPPS\PriceRetrievalTool
