Use robocopy for mirroring

Hello  everyone!

I use robocopy for mirroring some file resources at win2012 by using bat-file with scheduler.

But I have some troubles, and i can't find a resolution. Maybe someone could explain me:

Robocopy command: robocopy I:\folder \\serv\d$\folder /mir /zb /sec /w:1 /r:3 /LOG:folder.log

Scheduler event: an attempt was made to load a program with an incorrect format. (0x8007000B)

Robocopy log:

   Total    Copied   Skipped  Mismatch    FAILED    Extras
    Dirs :          534336      2939         0         0         0      2820
   Files :   4578130       77652     4500413    0        65     69383
   Bytes :   5.563 t  39.898 g   5.524 t         0   16.43 m   1.104 g
   Times :   3:20:52   1:10:21                       0:03:15   2:07:15

How can I analyze the scheduler event, and how can I find 65 "failed" files?

 Thanks for any help!
