I want to install both Halo CE and HEK onto my harddrive but it seems to not work especially with the patch. Has anyone manage to get this to work?

First and foremost, do you have a completely legitimate copy of Halo Combat Evolved?

ok. I have plenty of space on both my external and internal hard drives but my external is where all my work is. The thing is that I can put Custom Edition on my external but the patch only works with the default destination and HEK syncs with the default destination. :/ I need the patch so I won't have any stupid invalid key issues that will occur.
Someone has to have found out how to get it to work with any portables or crazy cracks.

We dont condone or talk about that here.

Grab the HCE and HEK installers from this site, install them to the external harddrive and update them.

Now, open regedit, if your in 64 bit windows navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft Games\Halo CE
if 32 bit, I believe its almost the same, just without the "Wow6432Node" in the path. Export this registry entry, it has your CD Key. If you installed it on 64, and think you might possibly play it on a 32 bit machine, or the other way around, make a duplicate of the exported registry file, and change the path to the other ##bit registry path with notepad. Now when you want to play it on a different computer, you run the registry that matches the bit, and go to the redist folder and run msxmlenu. There are some registry keys for a few HEK settings, but they don't particularly matter, as long as you have the programs and your tags.
