Hi,
Did you try to restart chrome (close all windows)

Already look this way, no resolution found.

[jcfrog]

It's vdhcoapp install (not --install)

While I'm running x64...

[jcfrog]

are you sure you downloaded the proper 64 bit coapp? https://github.com/aclap-dev/vdhcoapp/releases/latest/download/vdhcoapp-windows-x86_64-installer.exe

Yes, I'm sure
