Vistalizator - change display language in Windows Vista and Windows 7

Details

No need to install this program, just run it
Supports 36 Vista/Windows 7 MUI languages: most of them provide full translation of user interface
Supports Vista/Windows 7 LIP languages: they can be installed upon installing their parent MUI language:
List and download 32-bit Windows Vista LIP languages
List and download 32-bit Windows 7 LIP languages
List and download 64-bit Windows 7 LIP languages
Languages can be installed either in Internal or in Express mode, see below for details
Multiple languages can be installed in one go
Built-in conversion is used for MUI language packs in EXE format
Built-in file integrity validation is used when loading language packs (using MD5 checksum)
Changing to new/another MUI language is global for all users and requires system restart
Changing to another LIP language using the same MUI parent language requires current user to be logged off only
Different users can have different LIP language provided that the languages can use the same parent MUI language
Some troubleshooting command line parameters are available, see below

It's an experimental feature: successful installation is not guaranteed when installing MUI languages, LIP languages are installed without problems
Installation procedure used in versions lower than v2.00 is now called Express mode
Internal installation uses the internal Windows language installer (after some hacking to force that for MUIs, LIP languages are supported on every edition of Windows by default)
These languages are fully integrated to Windows and are updated by the system itself or by Service Pack installer
Internal installation can be performed only once for MUI languages (the hack simply doesn't work anymore): this limitation doesn't apply to LIP languages
To install multiple MUI languages, load all of them and change their mode to Internal
To install a dependent LIP language in Internal mode, its parent MUI language must also be installed in Internal mode and has to be the current display language
Internal installation takes longer than in Express mode (20 min for a MUI, 10 min for a LIP)
This mode is default for LIP languages when their parent MUI language is Internal and it is the current display language
LIP languages installed in Internal mode are also uninstalled by the internal Windows language installer

Uses a "quick and dirty" approach to install new languages and is not able to update all the Windows system catalogs
That's why the new languages are not recognized by Windows and they are not updated by Windows
Upon (automatic) installation of some Windows updates that affect language resources some features may not work: these Windows updates have to be installed within Vistalizator to manually update Express languages, see details in Help
Compared to Internal installation it takes about ten times less time to install a new language
This mode is default for MUI languages and also for LIP languages when their parent MUI language is not internal and/or is not the current display language
Safe use: no file is overwritten during installation (except for an upgrade of language to SP1)

/? or /h - display info about using parameters
/c - save registry backup at program startup and on exit
(these files are saved in the program's folder)
/p - show Internal installation progress
(to be able to cancel the Internal installation or to see errors in case of a failure)
