Hello. I had such an error but rather long ago. Unfortunately I don't remember all the details but you could try to do the followig: - check if the directory 'data' has read/write rights for your OS account (account under which you try to start postgres). - check if your OS account has the right to log on as service (Administrative Tools/Local Security Settings/User Rights Assignment) - check in Computer Management/Local Users and Groups/Users if your OS account is NOT the member of any group of users.
