Abel,
Eike has been heads-down working on the new version that will be its own
project...

Yes, there's code that copied network preferences... If one needs to
set a proxy server to access outside a firewall, that needs to be done
already in the installer and the installed IDE will need those same
settings. The code should be more careful to check that the folder
really exists. I assume it's this code here:
PreferenceNode configurationPreferences =
PreferencesUtil.getRootPreferenceNode().getNode("configuration");
if (configurationPreferences != null)
{
PreferenceNode networkPreferences =
configurationPreferences.getNode("org.eclipse.core.net");
if (networkPreferences != null)
{
ResourceCopyTask resourceCopyTask =
SetupFactory.eINSTANCE.createResourceCopyTask();
URI sourceLocation =
URI.createFileURI(networkPreferences.getLocation());
resourceCopyTask.setSourceURL(sourceLocation.toString());
int segmentCount = sourceLocation.segmentCount();
URI targetURI = URI.createFileURI(new File(getEclipseDir(),
"configuration").toString()).appendSegment(sourceLocation.segment(segmentCount
- 2))
.appendSegment(sourceLocation.segment(segmentCount - 1));
resourceCopyTask.setTargetURL(targetURI.toString());
if (resourceCopyTask.isNeeded(this))
{
resourceCopyTask.perform(this);
}
}

It sounds like something is wrong with the preference file that it fails
to load properly. Perhaps try deleting
<user.home>\.eclipse\org.eclipse.emf.cdo.releng.setup\setup-eclipse.xmi
and letting the installer create a new one...

Yes, after creating an empty file with the correct name, the installer copies it happily.

If I get this right, this is unrelated to the failed copy of the other file. The preferences field is filled from the "originalSetup" in AbstractSetupTaskContext.initilaize(), and I guess that original is supposed to be the file you mentioned. I tried deleting it, but it still fails.
The contents of the above file is:
<?xml version="1.0" encoding="ASCII"?>
<setup:Preferences setup:toolVersion="8" xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:setup="http://www.eclipse.org/CDO/releng/setup/1.0" installFolder="[...]\Oomph"/>
Unfortunately, I use Windows 8 and my user directory has accents (which I cannot change), could this be the problem? Is there a way to copy this file somewhere else and have it load from there?

Abel,
Accents! I see that the resource factory doesn't set set UTF-8 as the
default encoding so ASCII is used. It really should default to UTF-8.
Does the file contain non-ASCII characters? If you change it manually,
I think that setting should be respected from then on, but we write
other resources too, and any one of them could have this problem. In
particular the setup.xmi has a reference to the preferences, so you'd
have to change that manually too and start the IDE again.
Please open a bugzilla. Eike could fix that in the old code and
definitely it needs to be fixed in the new code...
