Did you download the latest SF Pro 11 build. SF 11 was published just prior to the acquisition from SCS, so there are a SCS and Magix builds. I recall iZ' Nectar Elements was included w/Pro 11. SF Pro 9 and 10 had the (DX) iZ mastering suite . Pro 13 includes iZ's RX and Ozone Elements and well as the legacy NR-2.0. noise reduction suite. The iZ DX plugs do not run on 64 bit Pro 12/13, They do run on the x86 Pro 13. I don't think iZ supports any of the locked SCS/iZ plug-ins.
