Not a 100% sure on this, but I believe that if you don't explicitly have the CR Viewer installer, then the Runtime is called via DLLs, and not a specific EXE. I think they are called from within this path:
C:\Windows\assembly\NativeImages_v4.0.30319_32\Sage100ERP.Reporting
C:\Windows\assembly\GAC_MSIL\CrystalDecisions.CrystalReports.Engine\13.0.3500.0__692fbea5521e1304\CrystalDecisions.CrystalReports.Engine.dll
and supporting .NET CR Libraries from here:
C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\
This is unlikely to be what IT is actually looking for, but I don't believe there's going to be an actual EXE in this case.
