I’m writing a Windows Form Application, that makes extensive use of datagridview and others .net components. When I run the application on a Win 7, it always crashes, saying the qtcore4.dll library is missing.
My question is: is this a normal behaviour? and this is happening only to me? and what does that library do?
Run Process Monitor and see where on disk it’s trying to load
qtcore4.dll.Then make sure you have a copy of that .dll installed on disk in that location.
Otherwise, you may need to start shipping it with your application in the same directory as the run-time executable.
