Builder requires a base installer which we combine with your interface and license to output the final installer. Builder can download this for you from the “Update Sources” button. If this fails because of proxy or corporate firewall issues you can download the file manually and copy it into the correct directory.
You can download the base installer here. The file is called “MegunoLink Host Installer Stub.msi”.
Once downloaded move this file here:
“C:\Users\Your User Name\AppData\Local\Number Eight Innovation\MegunoLink Builder\Host-MLP”
You might need to create folders if they don’t already exist.
