Alternative to "Allow service to interact with desktop"?

Question

I have a windows service (C#) installed on a server that launches every 10 minutes an executable file (C#) to process some images from one directory to another. No interaction is required with any user. Nevertheless, since the executable file as an output window, to make the service run I have to enable the "Allow service to interact with desktop" checkbox which is considered as an insecure and bad practice. How would I go about this problem? I like to have the executable separated from my windows service because

• it makes it easier to debug and doesn't require a full windows service redeploy.
• sometimes I use the same windows service to launch several executable files at different intervals (but all related to the same project).

EDIT:

When the interaction with the desktop is not enabled, the console application does not get executed correctly and the following error appears inside the Windows Logs:

Faulting application myapp.exe, version 1.0.0.0, time stamp 0x4b8304c3, 
faulting module KERNEL32.dll, version 6.0.6002.18005, time stamp 0x49e03821, 
exception code 0xc0000142, fault offset 0x00009eed, process id 0x10ec, 
application start time 0x01cab736950a64b5.

Once the desktop interaction is enabled, application gets executed normally.

Any thoughts?

Thanks a lot for your time.
