The installation actually crashes.
I've said it here also: #668.
And it crashes when it tries to insert the admin account.
Because of this line:
$this->setup->getConnection()->insert($this->setup->getTable('admin_role'), $role, true);
from the Magento\Setup\Model\AdminAccount::save().
The table admin_role does not exist anymore. It is renamed to authorization_role in app/code/Magento/Authorization/sql/authorization_setup/install-1.0.0.0.php.

Now, why do you get 96%...Because of the strange formula used to calculate the progress.
Magento\Setup\Controller\Install\ProgressController::indexAction

        $moduleCount = count($this->moduleList->getModules());
        $log = $this->logger->get();
        $progress = 0;
        if (!empty($log)) {
            $progress = round(count($log)/$moduleCount*90);
        }
        $progress += 5;

So round(number-of-lines-inlog / module-count ) *90 + 5.
There are 80 modules + the line Artefact installed added "manually".
So you get round(81/80) * 90 + 5 = round(1.0125 * 90) + 5 = round(91.125) + 5 = 91 + 5 = 96.

Next issue...
The data update scripts should run after the admin is inserted. https://github.com/magento/magento2/blob/master/setup/module/Magento/Setup/src/Controller/Install/StartController.php#L179
By the way Magento Team...is it absolutely necessary to use exec? Looks ugly to me.

If you change in the line I mentioned above the table name from admin_role to authorization_role the install should work. But You still get Looks like database is outdated. because there are some modules that don't have install scripts but the data install script seams to pick them up.
Run this query UPDATE core_resource set version = data_version,
Now your Magento2-alpha96 should run nicely.

All, we are aware of this issue and we are doing our best to get this fixed till the next deployment this Friday. Please be patient and wait till we deploy the code with the fix. Meanwhile, please use the console installation. Thank you all for reporting this!

@zhangjiachao , @tzyganu , could you, please, confirm that these issues are gone (or still present) in the latest versions?

1. installation stops at 96%
2. issue with admin_role table
3. application is not updated after installation and requests update ("Looks like database is outdated.")

P.S.: we're currently working on this issue with exec()

[tzyganu]

@buskamuza I can confirm that the installation does not stop anymore, I can also confirm that the admin saving process is not affected anymore by the admin_role table renaming and there is no more error message "Looks like database is outdated.".
I can also confirm that the install process does not take 2.3 eternities anymore. Just 1.2.
Last tested on alpha 104.
From my point of view, this issue can be closed.
