Open Contacts was designed to be portable since day one. The program can locate the working directory through start-in directory, command-line parameters or registry, depending on the start-up modes.

PortableApps Start Menu is a program managing portable applications, giving you a handy user interface of accessing portable programs installed in an external storage such as USB flash disk.

You may simply extract all files in the package into [PortableAppsRoot]\PortableApps\OpenContacts, and then refresh PortableApps Start Menu.
