    Ok first off I have no knowledge of registry problems or how to fix them.
    With that said I have been trying to get some help for a long time with two
    errors I keep getting. It all started after installing a update from windows
    update and up until now they had always been helpfull. I keep getting moved
    around and forwarded to different people and they have not been able to help
    me fix the errors so I am asking for help from anyone who can help. I would
    prefer help from someone who has had these issues and fixed them, but at this
    point I would greatly appreciate any help because error messages really
    bother me, even if it has not caused a problem yet.

    These are the errors I have got :
    1. ' AppInit_DLLs=' this one has two errors that show up.

    1st error message: "Cannot find the file ' AppInit_DLLs=' ( or one of it's
    components). Make sure the path and filename are correct and that all
    required libraries are available."

    2nd error message "Could not load or run ' AppInit_DLLs=' specified in the
    registry. Make sure the file exists on your compoter or remove the referance
    to it in the registry."

    This is what I have found about this but it is of no use to me because it
    does not provide me with a "fix" that I can do.


    Working with the AppInit_DLLs registry value

    The AppInit_DLLs value is found in the following registry key:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Windows

    All the DLLs that are specified in this value are loaded by each Microsoft
    Windows-based application that is running in the current log on session.
    Note This feature may not be available in future versions of the Windows
    operating system.

    The AppInit DLLs are loaded by using the LoadLibrary() function during the
    DLL_PROCESS_ATTACH process of User32.dll. Therefore, executables that do not
    link with User32.dll do not load the AppInit DLLs. There are very few
    executables that do not link with User32.dll.

    Because of their early loading, only API functions that are exported from
    Kernel32.dll are safe to use in the initialization of the AppInit DLLs.

    We do not recommend that applications use this feature or rely on this
    feature. There are other techniques that can be used to achieve similar
    results. For additional information, click the following article number to
    view the article in the Microsoft Knowledge Base:
    134655 (http://support.microsoft.com/kb/134655/) AppInit_DLLs registry value
    and Windows 95
    The AppInit_DLLs value has type "REG_SZ." This value has to specify a
    NULL-terminated string of DLLs that is delimited by spaces or by commas.
    Because spaces are used as delimiters, do not use long file names. The system
    does not recognize semicolons as delimiters for these DLLs.

    Typically, only the Administrators group and the LocalSystem account have
    write access to the key that contains the AppInit_DLLs value.

    AppInit_DLLs Registry Value and Windows 95

    This article was previously published under Q134655
    Windows 95 does not support the loading of a DLL into a process's address
    space through the use of the AppInit_DLLs registry value. In Windows NT, for
    every process executed, Windows NT loads the DLLs listed in the AppInit_DLLs
    registry value into the process' address space. For similar functionality in
    Windows 95, you can implement a system-wide hook. This article shows by
    example how to do it.
    To implement a system-wide hook, you must ensure that the hooked function
    (callback function) exists in a DLL. Then, when the this function is called,
    the operating system maps the hooked DLL into the target application's
    address space. The actual hooked function then operates as part of the target
    application's process.

    There are essentially two steps involved in creating a system-wide hook: 1.
    Create a DLL with an exported function that is used as the hooking function.
    In the sample function that follows, the callback function is modeled after a
    callback function required to implement a WH_KEYBOARD system-wide hook:
    // Trap keyboard messages
    __declspec(dllexport) LRESULT CALLBACK HookFunction(
    int code,
    WPARAM wParam,
    LPARAM lParam)
    char szVCode[50];

    //display the virtual key code trapped
    sprintf(szVCode, "Virtual Key code: %lx", wParam);
    MessageBox(NULL, szVCode,"Key stroke", MB_OK);

    The associated .def file for this DLL might resemble this:



    2. Install the system-wide hook. To install the hook, the DLL must be
    loaded, the hook function's address retrieved, and SetWindowsHookEx called
    with the function's address. Here's an example: // add system-wide hook
    hHookDll = LoadLibrary("hook");
    hHookProc = (HOOKPROC) GetProcAddress(hHookDll, "HookFunction");

    // Install keyboard hook to trap all keyboard messages
    hSystemHook = SetWindowsHookEx(WH_KEYBOARD,hHookProc,hHookDll,0);

    Once the application has finished with the system-wide hook, be sure to undo
    the hooking process as follows: // Remove the hook and unload the DLL
    used for the hooking process

    Sorry that was so long but I hope if I give all information I have someone
    might be able to help.

    The second error I get is when I run Nortin WinDoctor invalid file
    extension. This error is very problematic and once again I can find no "real"
    help on fixing it. This is what is stated by windoctor:

    Missing or Invalid Key: ".wll"
    The file extensions, ".wll", referes to an invalid identifier,
    "Word.Addin.8" it tries to delete the registry entry but fails everything I
    have tried has failed there seems to be now information from microsoft about
    this and all the message boards I have been to could not help me fix this

    My OS is Windows2000 Professional

  2. Do you have that value? What does it contain?

    If it contains a list of .dlls and you can't find one of them
    anywhere on your harddrive that would explain your symptoms.
    Also it probably would only be used by third-party programs.
    So, if you have installed or uninstalled some recently that would
    also be a clue for you.

    Why are you running Norton WinDoctor?
    If you don't do that do you have an error symptom?
    If not, don't do that. <w>
