When I try and create an installer it claims that three of the required run time installers do not exist on my system. It is requesting the 8.5 Run-Time, DAQ-mx 8.6 and Sound Vibration Run-Time. Additionally I know I also need the TDMS installer as well. But my list of "Additional Installers" does not seem to be filling out properly. It only contains the LabVIEW 8.0.1 Run-Time Engine, LabVIEW 8.2.1 Run-Time Engine and LabWindows CVI 8.1 Run-Time Engine. I know I should have more and a quick look in the ProductCache folder shows the following directory listing with MSIs in all of the important ones that I checked.  
Directory of E:\Program Files\National Instruments\Shared\ProductCache 
CVIRTE [8.1.1] 
lv80rte 
mkl700 
NI Certificates Deployment Support [1.01.49153] 
NI LabVIEW RealTime NB-FIFO [8.2.1] 
NI LabVIEW RealTime NB-FIFO [8.5.0] 
NI LabVIEW Rutime Engine [8.2.1] 
NI LabVIEW Rutime Engine [8.5] 
NI License Manager [3.2.1027] 
NI Logos XT [4.9.0] 
NI Logos [4.9.0] 
NI MDF Support [2.51.87] 
NI Service Locator [8.5] 
NI Sound and Vibration [6.0] 
NI TDMS [1.1.0] 
NI Uninstaller [2.51.87] 
NI USI UFF58 Plugin [2.2] 
Even a look at the "Software" section of MAX shows that I have the LabVIEW Run-Time 8.5.0 installed. Any thoughts on how Installer gets its list of installed components? I'm not real interested in doing another full install of LabVIEW DAQ-mx, SV Tools, and DIAdem just to get my installer to recognize them.
