Desktop Central 9 Post-deployment activity script not executing properly

I am using the software deployment feature of desktop central 9 to deploy a software MSI package. The software itself installs without issue through Desktop Central but I have a script set to run in my post deployment activity that is not working as intended. The script is supposed to launch the program after it has been installed. If I run the script from the local computer or even the network share myself it opens the program as intended but when it is executed through Desktop Central it does not. I will post the script below and any idea would be much appreciated.

@echo off

start "runbanner" /d "C:\Program Files (x86)\Banner" Banner.exe

echo Finished

As an additional note the computer it is installing to is running a 64 bit OS hence the x86 target.

The file is named runbanner.bat and it is located in the same folder as the MSI file on our network share.
