Standalone Installation - To install a portable app by itself, or manually, just browse to the location of the AppNamePortable_x.x.paf.exe file you downloaded. Double-click the file to start the installation. Follow the on-screen prompts and select the location you'd like to install to. If the installer detects an existing PortableApps directory on one of your attached drives or within your USERPROFILE folder, it will automatically select that. Otherwise, the current directory will be selected by default. Within the directory you select, an AppNamePortable directory will be created containing the portable app. Note that installing to the C:\Program Files or equivalent is not supported.
