Conrep not working on Server 2016, Gen10 DL360

I cannot get conrep to work on a Gen10 DL360 server running Windows Server 2016. I take the following steps:

1. From the scripting toolkit (v. 11.20), copy hpsstkio.sys to C:\Windows\System32\drivers
2. Make sure the file is Unblocked
3. Install the CHIF ilo driver
4. Unzip the contents of the HP scripting toolkit (v. 11.20) onto the server
5. Run, for example, "conrep -s -f current.xml"

The output on the screen is as follows:

c:\Program Files\HP\Toolkit>conrep -s -f current.xml
conrep 5.3.0.0 - HPE Scripting Toolkit Configuration Replication Program

        System Type:                    ProLiant DL360 Gen10
        ROM Date   :                    06/20/2018
        ROM Family :                    U32
        Processor Manufacturer :        Intel(R) Corporation

XML System Configuration: conrep_gen10.xml
Hardware   Configuration: current.xml
        Global Restriction: [5.00                            ]                  OK


Platform check:
                : [Gen10               ]        match

However, no file is created. Running "echo %errorlevel%" yields: -1073741819. So it definitely didn't execute properly but I don't know what the error code means.

Any help would be appreciated.
