Hello
api-ms-win-core-winrt-l1-1-0.dll is a windows 8 or later library, that's why the program, when trying to search that library in system, fails to start because this dll is not present in windows 7
Also, even if this dll could be somehow added, PlasticX is being developed in Net 6.0, and Microsoft only gave support in Windows 7 to Net 5.0, so running the application in Windows 7 is not possible
To be able to run PlasticX, a newer Windows version than Windows 7 is needed
