Well, it's all in the title. Adobe Premiere and Media Encoder can't use NVENC with Voukoder 6 on my PC. I was using Voukoder 5 with premiere connector 1.4.0. NVENC was in place, but voukoder started to show tooltips "new version available". I updated drivers to 452.06 coz in release note there was limitation of nvenc to driver version 450 and newer. Then I installed connector 1.5.0 (without uninstalling 1.4.0) and Voukoder 6 (also without uninstalling 5). Now NVENC is gone. It's strange... Maybe I'm missing something?
P.S. I uninstalled Voukoder 6 and installed 5. Premiere connector 1.5.0. Now everithing is fine, NVENC is in place. So there is some strange problem with new version of Voukoder and my old videocard:) And maybe Windows 7.
And another addition, I've found log files! Not so much info in them, but there is something.
