    Apparently permissions preventing VB code access to Windows\System32 folder

    Apparently my Access VB Code does not have permission to access the
    "C:\Windows\System32" folder. This code ran perfectly under Windows XP SP2
    before upgrading to Windows Vista.

    When trying to call a function from a dll file using VB for Access 2007 I
    receive the following error:
    Run time error '53': File not found: emdaz32.dll

    Normally the following code accesses the dll file:
    Declare Function DAZOptions Lib "emdaz32.dll" (ByVal lngHandle As Long)
    As Long

    However, even a full path returns "File not found" error message.
    Declare Function DAZOptions Lib " C:\Windows\System32\emdaz32.dll"
    (ByVal lngHandle As Long) As Long

    The 32-bit dll file exists in the "C:\Windows\System32" folder. If I
    copy the emdaz32.dll file to the "C\Users\Rick\Documents" folder and
    reference
    this full path in my VB code the dll file IS accessed when the code runs,
    however, this particular dll file must call another function from a second
    dll file which is presently located in the "C:\Windows\System32" folder AND
    the "C\Users\Rick\Documents" folder. I then receive the same "File not
    found" error for the second dll file.

    I'm the only user on this Vista 64-bit computer and of course have
    administer privileges. I get the same results with User Account Control
    turned on or off.

    The Current Owner of the "C:\Windows|System32" folder is "TrustedInstaller".
    As a member of the "Users" group I have "Read & execute", "List folder
    contents" and "Read" permissions. These are the default permissions and I
    can't change them. At least not while "TrustedInstaller" is the owner. I
    haven't tried to take ownership of the folder.

    Does anyone have any ideas what I might do to correct this problem?

    Thanks so much to anyone who offers help.

    Try running it 'elevated'. Right-click 'Run as administrator'

    I don't know the answer but you might find it on the MSDN forums.

    Re: Apparently permissions preventing VB code access to Windows\System32 folder

    As always... those of you that take time out your day to read these news
    groups and post your suggestions and solutions desire so much more than a
    simple text thank you. Unfortunately, that's all I can offer in this forum.

    Thank you for your help and thank you to Dennis with Microsoft who called
    with a fix.

    Installing Microsoft's Direct Mail Manager Update (v.2.02.0044) copied the
    dll files into the "C:\Windows\SysWOW64" folder.
    After installing this update my Access VB code runs perfectly without an
    absolute path to the dll file names.
    Declare Function DAZOptions Lib "emdaz32.dll" (ByVal lngHandle As Long)
    As Long
    It still runs great even after uninstalling the update because the dll files
    remain in the "C:\Windows\SysWOW64" folder. If I remove the files from this
    folder I experience the same "File not found" error as before.

    Apparently with Windows Vista I must copy dll files to the
    "C:\Windows\SysWOW64" folder.
    (Actually the update installed them in both folders so I've left them both
    in each folder.)

    Thanks
    Rick
