.exe will not run in DS job but runs locally

I am trying to install an application to a Windows 7 x64 PC with a scripted job on DS 6.9 SP5.  The job runs the application's setup.exe file and when it finishes, the job returns as a successful install but the application never actually installs.  If I run setup.exe locally or from the server it works as it should.

My scripted job is as follows:

rem Install Pictometry Extensions

\\servername\express\Deploy\Pictometry\Pictometry_10.0.33\setup.exe

Has anyone seen this happen before and have a solution?

Thanks for your help!
