If your computer is configured to boot more than one version of Windows, and you want Folder Guard to protect the resources of the computer for each of such versions, then you need to install and configure Folder Guard under each version of Windows that your computer is able to boot with.

For example, if you can boot your computer with either Windows 32-bit or Windows x64, then you need to install and configure one copy of Folder Guard after booting with Windows 32-bit, and then reboot with Windows x64 and install another copy of Folder Guard, into a separate folder, and configure it separately.
