how to run a cmdline program at a certain time hourly - daily, etc...

I have a program from here I want to run at a certain time few times a day. How can this be done?
Needs to include commandline parameters.

example is this idea.

zap2xml -z -u tvguideuser@email.xx -p password -o myfile.xml

I created a batch file, it works when manually run. Works great.

Task scheduler, wont run the batch file. I get an error 0x41303 when trying to hit run as a test.
That error message appears in the line for the task, and the task says it has never run. I do have run whenever selected too.
example of my batch file

Code:

@ECHO OFFECHO.
ECHO This is a batch file
ECHO.

zap2xml -u username@gmail.com -p password -o myfile.xml

CLS
EXIT

I set the task up in task scheduler to run every day, under advanced to run every 6 hours.
So it just is too hard to use if It does not work?
Is there an alternative task scheduler program which I can use?

I found a freeware, incredibly simply scheduler that actually DOES run the batch file, and it works. It generates a new XML file when I test run.
Only thing is it can only be set to run once per day, I want to run this every 6 hours.
BUT, at least it functions.

Freebyte Task Scheduler

I actually SOLVED this in win7, which should be same as win 10.
Even though this setting 'start in' says 'optional', you MUST entire the directory, cant leave it blank.
It runs everytime now I test run this.

If you want it to run whenever anyone is logged on, unselect the password, and you have to change the file permission to give everyone full control for the batch file.

can the batch be told to run minimized?
every 6 hours it pops up on the screen, runs till it finishes, then will close.
