Today, I did a second install of Music Production Bundle 2 and Insight asked to be authorised as before. I then did a seperate install of just Insight and did not ask to be authorised.

Thanks for the input!
 
I think I'll give it a go. No need to master in the next 10 days but I want the discount, so I think I will just buy it and skip the demo.

Been using the MPB for some time now... never had an issue on either W7 or now, currently on W10

neutron vst2 is hanging the cakewalk plugin manager's re-scans.  I need the vst 2 for other software, though it also will not scan in Samplitude.  At any rate, they have not sent me a functioning installer which will allow me to install only VST3.
 
ozone 7 vst and rx plugin pack still will not install, iZotope has taken to sending me the same installation package a second time, 12 days after I first told them it was still incomplete
 
I would say that my experience with izotope has been less than good.  It's a shame, since the multiband transient shaper in Alloy and now in Neutron are among the tools I rely on.

by installing on another computer and copying the VST3 folder to a USB drive I seem to have been able to work it out.  I was hesitant to do so, since I don't know what else the installer might do.  I specifically asked about it to izotope and they did not respond.  I guess I'll find out if it keeps working.

izotope put their bundle with Ozone 7 Advanced and a bunch of other plugs on sale for the price of Ozone 7 Advanced alone.

This is as close to a no-brainer as I have seen.  I had RX4 Advanced, so I qualified for that ADVANCED bundle for $200.  That's Neutron advanced, an upgrade from my Ozone 6 basic to Ozone 7 advanced, the latest RX plug-ins (but not the RX stand-alone app), plus some other stuff I may use from time to time.  That's a great deal.
 
It did not start off well.  Thanks to the other folks here, I found that my problems were all solved by disabling the VST2 versions in SONAR.  It works beautifully.  I love that Neutron track assistant and the masking stuff.
 
And I just discovered in Ozone that I can now save directly in MP3, plus there is a full auditioning mode for the various dithering and compression levels.  Importantly, Ozone can let you hear what artifacts you are losing with your MP3 compression.  There is a lot more being lost, even at 320 kb/sec, than I expected.
 
And now I am looking forward to the next version of Ozone that surely will have a Mastering Assistant, along the lines of LANDR.
