Just installed the OS Windows server 2012 R2 x86_64b.
The Urbackup Server service did not start automatically. when tried to manually start the service it gave error code of 1053.
I even tried C:\Program Files\UrBackupServer and double click on urbackup_srv.exe but it gave error. The progra, cant start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer.
Tried with this update https://support.microsoft.com/en-us/kb/2999226 but gave error : The update is not applicable to your computer.
