BDIS 2016 seems not to be available for download on BD servers. If you download the installer for BDIS 2016 either from BD Central OR as a trial ("bitdefender_isecurity.exe"), then it installs Total Security 2016 and not Internet Security 2016; there is no choice over which package to install. I have paid for IS2016 and NOT TS2016 (3-PC Bitdefender IS 2016 from PXS Distribution via Amazon, and received as a DVD case code). The case code doesn't work of course as it is impossible to install IS 2016 as it is not available on BD servers apparently. Three emails requesting a resolution to this and absolutely nothing back from BD other than the usual pointless (and irrelevant) "send us a screenshot" garbage. I need a direct link to an Internet Security 2016 installation and NOT to Total Security 2016 installation. Is this an attempt to force purchase of a more expensive product, even though people have already paid for their product that is not available?! I suspect customers will migrate to Kaspersky...
There must be other who have this problem. I've tried it on two modern computers, both with Win10 latest build and fully updated.
