I try to use NDI tools from Newteck in Windows version (because the mac version is not complete)
https://ndi.tv/tools/#download-tools
It is said :
"This program can only be installed on version of Windows designed for following architecture : x64"
here is the report ID : 422459084
THANKS !!! i am very limited in my use of windows on parallels because i work a lot with NDI. I had to buy a PC to continue to explore. I really hope we will find the sollution. NDI is in high évolution and it would be a big limitation that Parallels remains unable to handle NDI tools.
