    You don't have the necessary permissions to use the .mdb object

    Good afternoon,



    I have a bunch of old .mdb files that I'm trying to access, but it wont let me open or import the files into any software, tried with libre office, br office, access 2003, 2000, 97.
    Message showing is 'You don't have the necessary permissions to use the .mdb object', how to change the permissions, there is even a way to do it?

    Is there a way to make sure it is actually a access database? (don't have all details because its an ongoing investigation, we already have the current data, but also need older ones).

    Edit: (There isn't any .mdw files anywhere in the hdds)

    Are the files in a protected folder?
    Have they been encrypted?
    Are you prompted for a password when attempting to open the file?
    when you try to open the file is a file in the same folder as the database created having the extension .ldb

    i.e. test.mdb should yield a file named test.ldb in the same folder.

    .mdb files would be any version of access prior to 2007 I think.

    sounds like there needs to be to access the file. Google your thread title and all the links you will find say the same thing

    They aren't in a protected folder, have been copied from the original hd into my own.
    Probably not, but how to tell?
    No password prompt.
    There isn't any, it just instantly tell me that error message in portuguese

    Try opening the file using Notepad. If it is an Access mdb file you will see information related to that.
    See this link for more info http://www.mendipdatasystems.co.uk/c...ity/4594444323
    It may also indicate whether an mdw file is required as appears likely

    It doesn't mention mdw in that article tho, there isn't any 'PWD' in the file, and by the hex editor IT SEEMS to be Access 2.0, can't be a 100% sure.Click image for larger version.

    all the relevant links I found when googling your question - see here

    https://www.google.co.uk/search?clie...UTF-8&oe=UTF-8

    say you need the mdw file.

    If you haven't got it, I don't believe there is a way to sidestep it unless you can recreate the file - some of the links have suggestions for that, but I didn't dig deep enough to see whether they actually worked

    Thing is, I have the full hdd image saved, and haven't find any .mdw file in it. Is there any chance of the supposedly .mdw file having a different extension? I found a .mdw in a different hard drive but it didnt work either.

    your system, you tell me. Always possible I suppose but then it wouldn't work.

    mdw is about security so I doubt it will be easy but one of the links I provided talked about editing an mdw

    I found a .mdw in a different hard drive but it didnt work either.
    without knowing how everything was configured way back when, it might be the one you are looking for, but doubt it would work if your configuration and users have changed.

    Unless you can recreate the configuration and users for these db's plus the mdw as they were when in use I suspect you are wasting your time. There may be organisations out there who know a way to break in for a price. But they will want to know the provenance of the apps to ensure it is actually yours.

    I have all versions of Access going back to v1.0 so can convert the database to whichever version you want.
    However its a chargeable service based on the time required. See http://www.mendipdatasystems.co.uk/d...ion/4594459112 for more details.
    If you would like me to do this, please email me using the link below.

    If it does require use of a MDW file, that will make the conversion much more complicated.

    is it doable without the mdw file?

    Don't know as I've never needed to try that before.
    However, I can crack almost all Access security, including passwords, on MDB files.

    If necessary, I will need to work through the suggestions in the links provided and see whether any work.
    The conversion to a newer version is normally straightforward.
    All you would be paying for is my time.

    But you've indicated there is no MDW file on the hard drive image, so it may not be an issue.
    As previously requested, if you want me to assist, please send me an email.

    It seems there actually isn't a password in the .mdb file, can it still be linked to a .mdw file?

    I believe it can but it seems a strange thing to do.
    However, I've not done much with MDW files in the past 12-13 years.
    Why not run a simple test to find out?
