The original rendition of ParkControl (https://products.bitsum.com/parkcontrol/) was a 'Live EXE' download. Technically, it was an SFX with auto-run afterwards, but that was all transparent to the user.
By request, these builds are now available again, but they are not officially maintained.
Of course, we recommend using the Installer downloads (the regular downloads).
However, for those that want it, the live EXE downloads will be here:
