Freshly rebooted Windows 10, 1902, 64-bit.
balenaEtcher-Portable-1.5.56.exe (md5sum bf7259481638d926c948b27b8f9e5e38):
balenaEtcher-Portable-1.5.57.exe (md5sum 8a3dfdc6e1c5595addfc827ae1d04867):
balenaEtcher-Portable-1.5.79.exe (md5sum 49cb69d9094159bc8fd799d7a64d55a2):
no window, task manager shows 3 Background processes labeled “balenaEtcher” and one Background process labeled “Flash OS images to SD cards and USB drives, safely and easily. (32-bit)” (I think this is the portable .exe).
When I started today, version 1.5.56 was installed on my system. I believe I had used it successfully some months ago but I could not find the icon to start it, so I downloaded 1.5.79, uninstalled 1.5.56, installed 1.5.79 and attempted to use it. When it failed, I downloaded it again, compared MD5sums, and also downloaded the portable version. Neither the installed version or the portable version worked so I started this thread. I also opened an issue (#3088) on the github site.
