Same (Unknown bundle setup error: 0x2) here.
This isn’t really saying much, so I investigated it a little and
discovered that it is probably caused by missing cab5.cab in data that
are temporarily downloaded into
d:\TEMP_{b0e7b9db-fc54-4f22-a13e-ac65c5744b34}\Package
Cache{DC804676-5720-4929-A988-4DC6DA85FE23}v2.0\ (interesting this is
that they are being downloaded into drive D:, although Game Launcher is
on disk E, directory for installation is also on disk E: and system temp
is on disk C:)
I checked also files BootstrapperApplicationData.xml, in temp dir, there is indeed defined cab5.cab for download, although it is simply not downloaded and therefore KCD.msi installation fail
s.
