I have used VEGAS since ver.15. and then 17 Edit. I believe, that I made a second purchase of 17 Pro to get 18 Pro for free. I have sinced, purchased 19 Pro along with Boris Primatte Studio but have had, nothing, but, trouble... I have had to uninstall 17, 18 & 19.. trying to fix things... no luck. Last time I tried to install 19.. my screen said there was a problem installing 19, that a component didn't finish correctly... I desperately, need to have 19 work... My system says, also, there is a system 32 logi.dll module that cannot be found... so there is that, too... I have a Intel i7 7820X Skylake with 64 Gb of 2666 Quad Chan RAM, and a NVIDIA EVGA 1080 FTW My "C" drive is a 500 Gb M.2 Nvme but, is really full.. no room for anything else. I have a second M.2 with plenty of room, but, haven't been able to get 19 install to work... Help Me, Obe Wan Kanobi
