/bin/install and /bin/install-info result in a "Permission denied" error on Vista.
Vista uses heuristics based, amongst other things, on the executable name to detect install programs. Having "install" in the names of these executables causes Vista to think they need Administrative privileges to run, and so results in a "Permission denied" error when they are called without Administrative privileges.
This can be fixed by including the attached install.exe.manifest and install-info.exe.manifest in the /bin/ directory. These files override Vista's heuristics and tell it that the corresponding executables actually don't need Administrative privileges.
