I found out that lcdhost doesn't work and shows error 0xc000007b only on a clean install of windows 10. Using it on a system with upgraded windows 10 works fine. This makes me think that lcdhost misses some drivers or prerequisites on a clean system. I wish i knew which though.
Well now im completely puzzled. I've tried installing lcdhost while unchecking every single option during installation. This resulted in lcdhost asking for qt plugins. Then i've clicked the installer again, it removed the previous installation, installed it again and everything is now working fine.
This is very weird.
