I want to use this but..

Greetings and welcome to the forum.

Knoppix 7.4.2 will recognize a 64-bit computer and install a 64-bit kernel at boot.
This will help recognize more than 3+ Gb ram and will work with 64-bit uefi but
that's about it. This Knoppix, and earlier ones as well, only provide 32-bit libraries
to support apps.

You may research this forum and find how some of the advanced members have worked
around this to some success.
