In ConsoleApp, everything works without errors, but when an error occurs in the WindowsService, the error occurs in NativeMethods.SetupDiCallClassInstaller with the code "13".
I can not understand why this is done in a simple application, but it does not work in a working project. Please tell me, maybe someone knows the reason.
Thank you in advance.
With this helper, I wanted to limit the interaction with usb flash drives. WindowsService should regulate access to flash drives, will be installed on all computers in the company and for some users to prohibit the use of flash drives, and allow someone.
