Allow (by clicking "yes") Microsoft Visual C++ to make changes on your device to be sure that Golem could work properly
If you’re upgrading from versions prior to 0.19.x, be aware that Brass Golem Beta 0.19+ uses Docker for Windows. Docker for Windows comes with a new type of virtualization support: Hyper-V (Windows Server Virtualization) in place of the old Docker Toolbox. This virtualization change should provide a more stable environment for Golem nodes, but it does not come without difficulties.
Please be aware that if you are using any other virtualization software (for eg. Docker Toolbox, VMware), do not install Hyper-V as this could potentially impact performance. If you encounter any problems with Hyper-V you can still uninstall it, and try to run Golem with Docker Toolbox.
Also if you are a Windows 10 Home user you will not be able to install Hyper-V as it's not supported. Fortunately, we have kept Docker Toolbox support in this case.
After installation of Docker Toolbox restart your machine and then run Golem.
