Unable to add new components in Windows 7 [Solved]

I wanted to add IIS on my asus laptop with Windows 7 Pro x64 but it keeps failing miserably. I cannot add any new component. It fails with the error :

• French : Une erreur s'est produite. Certaines fonctionnalités n'ont pas été modifiées correctement.
• English : An error has occurred. Not all of the features were successfully changed.

It is not linked to my tuning of windows 7 professionnal as I have enabled back again services, tasks, auto run registry keys and startup shortcuts. I have also enabled again system restore for both C and D drives. Strangely, I had to temporarily rename the C drive to its original name (OS) to avoid strange errors when validating the new configuration. I found on the net that the following command line could help :

fsutil resource setautoreset true C:\

But it hasn't fixed my problem. Each attempt adds five Windows Error Reporting events in the Application events log like :

A few notes :

• STATUS_SXS_ASSEMBLY_MISSING : Culture is wrong ! Why the hell is it looking for German (de-DE) packages on my French laptop ?
• The log tells Reboot required: no but it asks for reboot anyway (even if nothing is installed!)

I have downloaded System Update Readiness Tool (100 MB) even if the ERROR_SXS_ASSEMBLY_MISSING error might not be fixed by this tool (not listed in the error table). After 25 min execution, no error were detected in C:\Windows\Logs\CBS\CheckSUR.log. Sytem File Checker tool (sfc /verifyonly) found nothing (aucune violation d'intégrité). Google search :

• An error has occurred. Not all of the features were successfully changed. : 8.000.000 results
• on microsoft.com only : 3.200 results
• with CbsPackageServicingFailure2 event only on microsoft.com : 2 results
• with WindowsWcpOtherFailure3 event only on microsoft.com : 1 result
• with WindowsWcpOtherFailure3 event : 20 results (including this blog)

Running the package manager by hand is a bit more explicit (I use the same name as in my French graphical user interface):

pkgmgr /iu:"Client Telnet"

Gestionnaire de package Windows Echec de l'opération avec 0x80073701 L'assembly référencé n'a pas pu être trouvé. Well this is the ERROR_SXS_ASSEMBLY_MISSING error found earlier in Component Based Servicing log (CBS.log). After some research with Process Monitor, it seems that TrustedInstaller.exe fails to open the registry key HKLM\COMPONENTS\DerivedData\Components\amd64_microsoft-windows-s..oyment-languagepack_31bf3856ad364e35_6.1.7600.16385_de-de_08eb0375be2e567f. I can confirm this with regedit : the de_de key is missing, I only got these versions : el-gr, en-us, es-es, fr-fr, he-il, it-it, nl-nl, pt-pt and zh-tw. Note: HKLM\COMPONENTS might be missing on Windows 7. In this case, it would be generated completely if you launch Windows package manager UI. These keys matches files under C:\Windows\winsxs. I cannot find the de-de files in this folder. This is what Andre Ziegler told me in the forums. He also confirmed that I need to reinstall Windows 7 (again :( ). If I look into C:\Windows\System32\catroot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}, I can find all language files, and the German file in particular (like Microsoft-Windows-Shell-InboxGames-Package~31bf3856ad364e35~amd64~de-DE~6.1.7600.16385). As adviced in Win7 Inside Out - WinSxS, I have launched language packs setup application lpksetup but German pack is not installed (as expected : manifests are missing). Note: WinSxS = Windows Side by Side assemblies. Thanks to mydigitallife, I have downloaded German MUI pack : windows6.1-kb972813-x64-de-de_399ac15b2d55fd5dea0770d98825d7e75f4ad533.exe. To install this pack :

• Run pack exe to extract lp.cab file
• Download vistalizator
• Choose add language
• Select lp.cab file
• Validate language installation
• Make German the new display language : no !

It is now possible to add new features. Victory !
