SCCM 2012 .cmd file package deployment - 'Failed'

Hi.

I have created a package that runs a .cmd file to deploy an .exe file silently (with a response file)

When i deploy it, the application installs successfully to the target machine, however in 'Software Centre' it just says 'Installing' as if its still installing and eventually says 'Failed' with 'Error: 0x103(259)'

Do i need to send something back to SCCM to say the application has installed successfully? i.e. something in the .cmd file? Or does this error relate to something else?

Cheers

Neil
