Interesting Issue

    Hi,

    We are installing some updated software where I work, Sunrise Enterprise.

    We have been experiencing some random issues, never quite the same.

    Now we have had two versions of the software, and client software,
    Client32, refers to an INI file in the software folder to find the path
    of the database configuration file.

    The path was "Enterprise 5.0". There is now an "Enterprise 6.0" and to
    ensure no mismatches, "Enterprise 5.0" was renamed "Enterprise 5.0 OLD".

    Now, some of these paths weren't updated correctly. So we fixed this on
    Windows XP by modifying the INI file. And that then just worked.

    Windows Vista on the otherhand...

    We change the INI file using Notepad, everything looks fine, but the
    program does not appear to pick up the change. We know this, because it
    does not provide the expected login screen. If we restore the Enterprise
    5.0 folder on the network, then everything kicks into life.

    Removing the 5.0 folder again, and Vista breaks.

    We check the INI files in Notepad again, and they all point to
    Enterprise 6.0. We also check the registry, and there is no reference to
    Enterprise 5.0.

    There's something we're obviously missing.

    I would be very tempted to query whether when querying the INI file,
    Vista is reporting an outdated "shadow copy" of the file, for some reason.

    However if I log into the Vista PC as another user, or even Run as
    Administrator, then the software works and correctly picks up the
    Enterprise 6.0 folder.

    Im very confused.

    Do you have any thoughts as to what might be happening?

    Thanks
    Simon

    Very much a guess but have you considered "Permissions". Maybe something
    in the network is not letting the Vista machine read the file, or maybe
    Vista regards the file as somehow unacceptable?

    The INI file references a CFG on the server.

    The INI file is locally based. The local users are set as local
    administrators on the local machine. Security and permission for folders
    has been checked a number of times.

    The CFG file of databases on the server is correct as it works with
    Windows XP machines.

    The INI files must be correct because logging in as a different user on
    the same Vista machine is good.

    There isn't a problem accessing the CFG on the server, because the same
    troublesome user can run another program that references a different INI
    but the same CFG successfully.

    This leads me to believe there is some stale path set somewhere under
    that specific user - whether physically under UserData somewhere or in
    Registry - But I cannot find this. This then leads me to wonder whether
    the INI file is being "cached" in someway for this particular user?

    There are no other things that I can possibly think of.

    Check the shortcut to see if there's some absolute path in it?

    Sorry if this is no help but now 2 of us are confused :)

  5. Hi Simon

    Is the INI fle under the "C:\Program Files" directory?

    If so, you may be seeing a side-effect of file system virtualisation:

    Common file and registry virtualization issues in Windows Vista
    http://support.microsoft.com/kb/927387/en-us

    For security reasons, Vista does not like having user-edited files under the
    %ProgramFiles% directory. They should be kept under %AppData% or similar
    location. A future, Vista-compatible version of the software in question
    will probably fix this issue. In the meantime, look for the INI file in the
    virtualised location, %userprofile%\AppData\Local\VirtualStore.

    Hope it helps,

    So if being "User editable" is the cause how come other user's versions
    of the INI are accepted. Is it because that "User" may not be the one
    who edited the file?


    This appears to be a problem that exhibits itself in a pseudo random
    manner making diagnosis a real PITA.

  7. No idea if the 927387 issue is the correct or total explanation for what the
    OP is seeing. It just seemed a possibility worth investigating.

    If user 1 edits the foo.ini file and saves the changes, the updated version
    might really be saved in:
    C:\Users\User1\AppData\Local\VirtualStore\foo.ini

    When User 1 looks at the updated foo.ini file, it *looks* like it is in
    C:\Program Files\<some app>. But it isn't. If User 2 looks at C:\Program
    Files\<some app>\foo.ini, they see a different file, without the updates
    made by User 1; albeit apparently in the same location.

    Weird behaviour of this kind has been reported by previous posters to this
    newsgroup, and it was isolated to a side effect of "Program Files" directory
    virtualisation described in 927387.

    Buy that man a drink.

    Spot on.

    Knew it had to be something like this, but I couldn't find it or explain
    it. So thank you very much for your detailed reply.

    Much appreciated.

    Simon
