Had to re-install Windows 8.1 on my machine and then found I needed to download Faster Rename again, but I can't find license email.
Unfortunately, it's impossible to request a new license code based on your purchase because the official website and its developer are out of business. You will need to use another application because this one isn't available anymore. I recommend using the database of Software Informer to look for another application from this category. I have already linked the database word to a precise search containing the renaming applications.
