Thankyou for looking
(Or if the problem is that you try to install an older version of dnet, and that is being block by a newer version?) - this is exactly it.
I select the dnet 1.4.2 "autorun". Then "LV7" directory.
This brings up the "Features to Install". Everything is checked-including LV7 support. A message on the right says "This feature will not be installed." "A Higher feature of this product is already installed on your computer"
I am unable to uncheck.
Best Regards
