Hello,

I have 2 Applications. One is running in the User-Environment and one is running as system-Service. Both on a Windows-Machine. They use a File for some puposes and I want to secure the File-Operations with QSystemSeaphore. This works as Long as the Applications run under the same User-Environment. But I get a "permission denied" error if the Service locks the Semaphore and the User-Application tries to aquire it. How can I alllow the QSystemSemaphore for all Users?
