Set up Scheduler for a Domain

[x75]

Hi,
I would like to create a corn Job to run an Application for one of my customers.

But I can't figure out the cottect path to put in the "Command" Field. I'm trying to use the "Scheduler Manager" that you find when you open a Domain in Plesk, not the one under Server.

When I enter the complete path for the app ("D:\....") it emails me:
------
Started: Thu Dec 09 14:36:28 2004
as user: techkon
Process (D:\websites\vhosts\techkon.de\newsletterMail.exe --Johannes@x75.net) Can't get short process path for the (D:\websites\vhosts\techkon.de\newsletterMail.exe)
----

When I just enter the Filename it tells me It could not find the File.

So where in the domain folder should I place the File,
and what should I enter into the Scheduler ?

Thanks for any help
Johannes
