Steam DRM failed with Access Denied using 480 Test AppID

I’m trying to wrap my game with Steam DRM wrapper. I follow the tutorial here https://partner.steamgames.com/doc/features/drm

In Steamcmd, I use dram_wrap command with test AppId 480 after login as bellow.

drm_wrap 480 "D:\MyProject\Binaries\Win64\RBVR.exe" "D:\Steambuild\MyProject\Binaries\Win64\RBVR.exe" drmtoolp 0
Here is the error message in the console:

DRM wrap failed with EResult 15 (Access Denied)

The error log contains the exact same sentence. I’ve check that both files have read/write access.

Does anyone know how to fix this? Thank you in advance.

I took a look at my DRM batch file, it has a different format

steamcmd +login username password +drm_wrap 480 etc…

So, login details.

Thank you for reply. I run login command in a separate step. I’m sure that I’ve successfully login but the error still exist.
