Not working. Any tips?

[ZorroAVN]

I've cloned the repo to /opt

when I run:
/opt/pth-toolkit/pth-wmis -U username%password //IP 'cmd.exe /c whoami > C:\output.txt'
Note: I am absolutely sure the username, password, and IP are correct. And that the user is an admin.
I get the following response:
[wmi/wmis.c:172:main()] 1: cmd.exe /c whoami > c:\output.txt
[wmi/wmis.c:130:WBEM_RemoteExecute()] ERROR: IWbemServices_ExecMethod.
NTSTATUS: NT_STATUS_OK - Success

If I run:
/opt/pth-toolkit/bin/wmis -U username%password //IP 'cmd.exe /c whoami > C:\output.txt'
I get the response:
error while loading shared libraries: libtasn1.so.3: cannot open shared object file: No such file or directory
sometimes the response is:
error while loading shared libraries: libgnutls.so.26: cannot open shared object file: No such file or directory

If I go to /opt/pth-toolkit/lib:
I notice that both of those lib files are there (libtasn1.so.3 and libgnutls.so.26), but they are not executable like the other lib files in the directory.
Could that be the problem?

Any help or tips would be much appreciated!!
Thanks!
