When R service(in-database) installed in SQL 2016 Enterprise Edition, The launchpad service worked fine. After two days, the service was stoped and it can't be re-started again. The popup message is "Error 1053: The service did not respond to the start or control request in a timely fashion". In the log file EXTLaunchErrorLog, the message is "SetNecessaryPrivileges failed. ErrorCode: 0x80040004".
I would appreciate any help!
Thanks,
