Good Afternoon

I'm trying to run nBackup Firebird through command line below

C: \ nbackup.exe-U sysdba-P masterkey-B 0 C: \ nomedobanco.FDB C: \ nomedobackup.TMPNBK

but it appears to me the following error

The application failed to initialize properly (0xc000007b). Click OK to close the application.

What to do? Someone has gone through something similar?
