Hey, I tried to run NB 10.0 VC2. I use the Windows Defender SmartScreen and it was still activated since I don’t know. NetBeans 8.2, NetBeans 9.0 and NetBeans 10.0 VC1 opened very well (NB 10.0 VC1 with the command line but I think that was fixed). Now when I start NB 10.0 VC2 I got the Windows Defender SmartScreen prompt that my PC Prevent the start of an unknown app with only one call to Action called „Don’t execute“. There is a link for „More Information“ where I can still run it. Similar message on pages with http and HTTPS.
So IMHO smth weird happened from VC1 to VC2. Maybe with the HIDPI stuff? Only guessing, I don’t know. Cheers Chris
