myweb.zip contains all the files that you need to emulate a PC running Linux in Windows. Unzip this file to a drive to use it. This component can be installed on a portable USB drive for portability. There is nothing to “install”, just unzip the file. It should create a folder called myweb in whatever folder you unzip into.
Inside myweb, you should find Kqemu-1.3.0pre11-install.exe. This is the installer of the QEmu accelerator. It is not strictly needed. However, it does help to make things more efficient. Note that the installation of KQEmu requires administrative rights. Also, you cannot carry this component around on a USB portable drive. Run the executable to install the accelerator.
