Windows service & update C # console application

I have a windows service that runs a console application every hour, and it works without problems. I have not installed this though, and I am not at all familiar with Windows services.

Today I had to update the console application, so I suggested that if I just copied the exe file back to the folder, it would be called from the Windows service after I changed it, it would be nice. But it looks like she stopped working.

I started the console application from the command line and everything works fine.

Any ideas on why this might stop working?

thank
