    after a crash last year (while installing updates) the file
    NapiNSP.dll in C:\Windows\System32\
    and its cached copy in C:\Windows\winsxs\x86_microsoft-windows-n..ider-
    has got 0 KB in size.

    I tried all i found online or what i thought by myself could be

    - Deinstallation of Hotfixed installed that day and re-installed

    - copy a working dll (got it from a friend) to the winsxs folder using
    (that said "ok, but you have to restart to take effect" - but nothing
    happened after that

    - copy working dll to system32 using inuse
    (doesn work either: "c:\Windows\System32\NapiNSP.dll is protected by

    - sfc /scannow or /scanfile creates error log C:\Windows\Logs\CBS:
    Hashes for file member \SystemRoot\WinSxS\x86_microsoft-windows-
    \NapiNSP.dll do not match actual file [l:22{11}]"NapiNSP.dll"
    PublicKey neutral in the store, hash mismatch
    Cannot repair member file [l:22{11}]"NapiNSP.dll" of Microsoft-Windows-
    Naming-Provider-Infrastructure, Version = 6.0.6000.16386, pA =
    PROCESSOR_ARCHITECTURE_INTEL (0), Culture neutral, VersionScope = 1
    nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral,
    TypeName neutral, PublicKey neutral in the store, hash mismatch

    since the crash there's a popup error window everytime i start IE or
    other programms.

    Anybody an idea how to fix that file without reinstalling vista?
    System: Windows Vista Ultimate

    Thank you for any help

    Best regards
