When trying to install Piwik on my local webserver (XAMPP, Win XP SP3) the recognition of the installed PDO and MySQLi extensions seems to fail (see attachment), therefore the installation fails.
With Piwik 0.4.3 the installation and handling was flawless with the same configuration.
Keywords: 0.4.5, installation, pdo, mysqli, php extensions
Attachment: screenshot installer error Piwik 0.4.5
