Amadeus Vista & Cruise Product Upgrade for Microsoft Windows XP SP2
Technical Release Note

Impact of Microsoft Windows XP SP2 on Amadeus Vista and Cruise Products

Amadeus is in the process of upgrading the Vista and Cruise applications to fully support the robust security features offered by Microsoft Windows XP Service pack 2. Until a final upgrade release of Vista and Cruise is ready for deployment, one of the Service Pack 2 enhancements must be disable in order to ensure compatibility. Detail regarding the changes required follows.

Amadeus Upgrade content

Allowing Amadeus Product launch

The Amadeus Upgrade modifies three registry values.
The first two values are the following:

Software\Microsoft\Windows\CurrentVersion\Internet Settings\Lockdown_Zones\0\2101
Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0\2101

Those 2 values are stored in the “current user” store and are both DWORD type. The Amadeus upgrade sets their value to zero, therefore allowing the opening of local content pages.

Disabling the security banner temporarily

With only those two modifications, the Amadeus product will start but with a Security alert (called banner afterwards) displayed by Internet Explorer on top of the Vista window. This banner is warning the user that active content is trying to be shown in the window.

With such a banner, the user has to manually accept to run local content to start the Amadeus product. This is done by clicking on the banner and selecting “Allow blocked content…”. After that action, there is a last prompt to be accepted by the user and then Amadeus product will run normally.

By default, those operations have to be done each time the Amadeus product is started. Amadeus upgrade automatically ticks this check box; this is achieved by setting a third registry value. This key is also stored in the “current user” store and is a DWORD type set to zero

Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_LOCALMACHINE_LOCKDOWN

Finally, as Amadeus desires that the upgrade be applied only once, a special file, called marker and using the XML persistent technology, is automatically set, so that the upgrade is not applied again if the marker is found.
