Stand alone download for Dell Diagnostic software

I work for a large company and we manage hundreds of workstations, all of them Dells.  Currently if I want to run the diagnostics (based on PC Doctor) from the support website, it will install the required software and this can take 5-10 minutes.  I was wondering where I could download a stand alone package to pre-load our workstations with this software.  This would make the process faster.
