Oh, ok, Let me explain better. I downloaded the LGPNST package from the first page. Inside it it has several folders, One says 'Install me 1st', then the second says 'Install me 2nd' I can install those just fine. However when I get to the folder 'Install me 3rd' and I try to install the file 'LGNPST_Components_Ver_5_0_12_0.msi' within the folder I get "Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run."
I've downloaded the LGNPST package twice to see if it was a bad download but till get the same error message.
