I'm not using thinstall but archiving my (installed) games with RAR, with the necessary registry entries, instead. And I take great care to modify the registry entries, config files and sometimes executables, too, to make these "rips" work from any directory of any disk. (UnRAR the rip; import the registry file, if any; run the config program, if any; launch the game.)

Most of the time, this only means changing the appropriate registry entry to ".", ".\" or similar. The rips need to be launched directly from the directory they are "installed" so that that directory becomes the working directory (see "Start in" in the Properties window of a desktop icon for what the working directory is).
