Hi, I have a installation project, before installing my application, I need to install a VC redistribution. Sometimes the Shell.Execute returns 23, sometimes it returns 1638. I think only a return value of 0 means that it runs correctly. So I try to get the last error ,but the Application.GetLastError always return 0,Could you tell me how to find the means of the return value of the Shell.Execute.Or why the Shell.Execute does not return 0?
