Windows Vista Support

It’s been a while since the last update to MouseImp code. As recently reported, MouseImp had issues in Windows Vista. I have traced the code and made several modifications to MIPro.DLL in order to fix these issues. It seems now that basic functions work correctly in Vista.

Download updated MIPro.DLL with Windows Vista support

If you detect any bugs or issues, please post them here as a comment to this article.

Note: this version of MIPro.DLL does not support Mozilla FireFox, as I don’t have the source code for the one that does. However, there is an excellent plug-in that does exactly what MouseImp has to do, only in FireFox. It’s called Grab and Drag, and can be downloaded from

Update: the Vista capable MIPro.DLL is now part of the main distributive. If you are new to MouseImp, you may simply download the full version of MouseImp Pro Live!

    the newest version mouseimp pro works fine with vista explorer,but no action in ie7(vista os).thanks for the message “”,i had searched the same function software in firefox,and no one is suit for me.
    by the way,can these function fill in one mipro.dll?

  2. aoleg says:

    I’ll try. I assure you, however, that the latest MIPro.DLL works fine with IE7. You just need to stop MouseImp if it was running, replace the DLL with the new one (if the system does not let you do this, rename the old DLL). Then log off and log on into Windows (or simply reboot your PC).

    unfortunatly,it does not work in my ie7,under vista os.
    another question,in this article,the download dll, href is “Download updated MIPro.DLL with Windows Vista support”,size is 88k,while the newest miproLive! setup programe installed the mipro.dll file size is 52k,but i didn’t feel what differents they are.

  4. aoleg says:

    I guess I’ll just make a new installation distributive once the DLL is fully tested. BTW, try setting MouseImp for the RIGHT mouse button to check if it’ll work in IE7. I have just figured myself that the MIDDLE button does not work with IE7 for some reason, but the right one does. I’ll try to fix this one as well.

  5. aoleg says:

    I updated the installer, so the default download now contains the updated MIPro.DLL with Vista support. If you are updating an existing installation of MouseImp, make sure to exit the program first, then install the update to the same folder, and then reboot Windows. If you don’t restart your computer, the old MIPro.DLL can not be deleted, so the patch won’t work.

    Dear Sir,
    I really like to use MouseIMP,it’s very useful utility to scroll up/down window. Recently I upgrade to outlook 2007 and I found MouseIMP can’t work with Outlook 2007. I am looking forward to have revised version to fix this problem.


  7. aoleg says:

    There’s currently no MouseImp fix for the Office 2007 applications. Apparently, a new scrolling method is used in Office 2007. I will investigate this issue some time in the future, but no promises here. I’ll keep posting updates on this matter.

    hey guys,
    just checked your already brilliant app.
    but why is the function of my right mouse button totally occupied by mouseimp????
    with it running I no longer can use my convenient StrokeIt.
    Please help me!!!

  9. aoleg says:


    You can assign the middle mouse button in MouseImp, thus releasing the right one. That’s in Configure – Direct Scroll – Activate on – Middle Mouse Button

  10. Hannes says:

    sorry – found out, that after shutdown strokeit worked without obstacles in the next windows session.

  11. Hannes says:

    But another conflict:
    i have unchecked auto scroll in firefox but nevertheless mouseimp wont work.
    could you leave any tip?PLEASE!!

    regards from stuttgart,

    Hello Mouse Imp fans.

    To make Mouse imp work in Firefox just install ” Scrollbar Anywhere “.

    Get it Here:

    Note that the settings conflict. Just leave the boxes in Scrollbar
    blank and Imp will control.

    Their is no Scrollbar for Thunderbird but Grab and Drag works
    in TBird without ImpMouse.

    Thanks very much to the kind persons who fixed Imp to work with
    Vista. I have been using ImpMouse since long before it was free.
    I really missed it.

    WELL DONE !!!

    MouseImp Pro (live) does not seems to work in MS Outlook applications like Outlook and Word. Is this a known problem? Any solutions to expect? Thank you.

  14. Peter says:

    BTW I was talking about Office 2007. Peter.

  15. Victor says:

    Thanks for the update which enables MouseImpPro to work in Vista. It works fine in Avant and Maxthon. However, it doesn’t work in Opera 9.2 – perhaps you can restore Opera compatibility eventually? Thanks for this great little utility.

  16. aoleg says:

    Finally, there is a test version of MouseImp that supports several Microsoft Office 2007 applications. See main page or download from here:

  17. DentAr says:

    Wonderful! Even without the source code to support Firefox – using the ‘Grab and Drag’ plugin is a very good solution (the best actually for me).
    Just wanted to say ‘thank you’ for continuing in development. Keep up the good work!!!

  18. DentAr says:

    Hello all,
    wouldn’t it be wonderful to have MouseImp running in Windows XP x64 or Vista x64? Is this version of MouseImp compatible with the x64 windows’ ?
    If not, please, please, please compile a MouseImp64 release!!!
    (this would definitely make my day)

  19. aoleg says:

    > Is this version of MouseImp compatible with the x64 windows’ ?

    I don’t know! I don’t have the 64-bit version handy, and can’t test it. If you have Vista64, would you mind installing MouseImp for a quick compatibility test?

  20. DentAr says:

    Ohhh, wonderful – this site is not dead yet!!! (smile)
    Well, i do not have any vista64 versions at hand, but i am installing windowsxp64 at the weekend. And, of course i will install mouseimp for a test (can’t live without it any more)
    The problem i see is, that e.g. explorer is a 64 bit application (using 64 bit dll’s) and mouseimp is (??) 32bits. So the call from a 32bit dll to a 64bit dll (and vice versa) does not work anymore.
    WinXp64 has, of course, a WOW64 implementation and there is another explorer (32 bit) which might allow mousimp to run.
    Speaking of native 32bit apps running in xp64, well i might think mouseimp must work as expected.
    But, the test results will follow after this weekend…

  21. DentAr says:

    ok, here are the results of running mouseimp in WinXPx64: As expected, it runs in a 32bit process and all other 32bit software is working seamlessly with mouseimp. But, all native 64bit software does not see mouseimp – this is especially annoying for e.g. windows explorer. Any ideas of compiling a 64bit mouseimp? (i will be happy to test it…)

  22. aoleg says:

    I’ll see what I can do for x64. So far it seems that you’d need to run two versions of MouseImp simultaneously; one for 32-bit, and one for 64-bit applications. I don’t have any experience in developing hook DLLs for the 64-bit environment, let alone support 32 and 64 bits in one binary. If someone who does comes along, please email me!

  23. Cyril says:

    hi aoleg,

    thank you very much for this piece of work, the best out there im telling you. thought im on vista x64 and it doesn’t work on native x64 apps, but still gotta say this thing rocks!

  24. Charles says:

    :( Still no updates for x64? I wanna run it on Win2008R2.

  25. aoleg says:

    Supporting x64 would not, unfortunately, be a simple update. A major rewrite is required. I don’t have the required skills to do this. The source code is old, and hardly portable.

  26. Jason says:

    Hey guys,

    For x64, I found Scroll Navigator. Thing is, it costs money and is not as fluid and smooth as mouse imp pro. Good work aoleg! And thanks for having looked into a port. I guess someone else will have to implement or we just wait for something else to come out. Man, such a great tool.

  27. aoleg says:

    Let me add a link to Scroll Navigator:

    If I decide to upgrade to an x64 system, this will be the first thing I’ll use.

  28. tbone says:

    ScrollNavigator does not do it for me on Win7-x64.
    Either choppy scrolling or nothing at all.

    MouseStar might work better for some of you, but is unfortunately not as straight as mouseimp was, so again no options until now.. o(
