    How to use Winmail on Windows 8.

    Here's a solution for all who want to use winmail and windows 8.

    The procedure is almost the same as windows 7 , but we will need a dll file.

    First , we do the same procedure as in windows 7 :

    a) Take ownership of winmail forder ( if you use windows 8x64 , you need to take oweneship of program files/winmail and program files(x86)/winmail). Remember to check the " show system files " before that.

    b) Delete all the files in winmail forder and replace them with the windows 7 / winmail files.

    c) Copy msidcrl30.dll to c:/windows/system32 folder

    d) Now , we have to register the above dll. Open cmd and type : regsvr32 "c:/windows/system32\msidcrl30.dll" and press enter.

    Reboot , just in case , and you're done !!

    windows 8

    When i register regsvr32 "c:/windows/system32\msidcrl30.dll" i get the RegSVR32 message saying the dll is not compatible with the x86 ver of win8 i'm running.

    Repeated process (after reboots) but still doing something wrong.

    Just recalled that i ran "WinMailEdit" prior to starting instructions in this post - could that be my issue?

    Any ideas?

    1. I have got windows mail from vista working on w8 beta. You have to save the mail prog for vista (32 or 64 bit) according to which version of w8 you use. I use 32 (not tried with 64 bit). Then change permissions of windows mail in W8, bit of a pain, delete the files and the en-us folder, then copy the vista windows mail files to the windows 8 mail folder. Received an error message about msidcrl30.dll, but downloaded version c.1.7100.0, put it in windows\system32 folder and it works. Think problem was with the later version.

    i'll just wait a bit for Windows 8 Consumer Preview version & give it a go then...i've used the workaround several times successfully with win7 32/64bit. i most likely just botched my initial effort with win8.

    I use Windows 8 Consumer Preview 32 bit.

    The msidcrl30.dll from the download above seems to be the 64-bit version? It doesn't work on my system.
    My Windows 7 version (32-bit) also doesn't work.

    Who can help me with a working msidcrl30.dll version so I can use Winmail in Windows 8 CP? Thanks...

    Vista/Win7/Win8/Win10 (x86/x64)

    Just for fun I installed WinMail onto Win8 this afternoon (May, 2012) to play a little...
    I was surprised to see that MS must have intended to use WinMail on 8 since for whatever reason 8 comes stock with the Program Files/Windows Mail folder like it did on 7, but neither was activated unlike on Vista where of course the same WinMail files works as is. On 7 & 8 (& now 10) successively MS had built even newer version WinMail files too, but again upon each OS's release WinMail was not activated and so all by themselves the files would not start WinMail until retro modifications were made, similar to what we did on 7 but certainly is a different process here.

    Doing a little work on 8 transferring files from 7 and a few other things although not exactly like it's listed in posts above; iow, I did not need to regsvr the msidcrl30.dll, it works without regsvr, besides it gave a dllregisterserver error when I did. You do not need a specific version of msidcrl30.dll either since I tried many different versions and they all work, but might as well just use the current msidcrl30.dll out of 7 as it is today since WinMail works well with it there. The lack of information and dual zip/rar files attached to the first post is incomplete.

    When I went to delete the existing Program Files/Windows Mail folder with the necessary permissions, at first I started typing the cmd's out but was a p.i.t.a, so instead I used our forums administrator Brink who created This neat little Add_Take_Ownership.reg to do it quicker, with benefits. After that then right click on the Windows Mail folder, Take Ownership, and then deleted the folder. Copied my existing 'working' Windows 7 (or Vista) Windows Mail folder over to Windows 8 (I have my own so didn't need to use the incomplete files attached to the first post) Next I merged WinMailEdit.reg (as of June, 2015 now supplied at the bottom of this post) This registry file is nearly identical (minus SxS keys) to the WinMailEdit.reg offered over on the WinMail Windows 7 thread for its benefits, which makes WinMail more accurate for all the reasons that have been discussed over the years within the WinMail on 7 thread. The same process applies to Windows 8 or 10.

    Note: The first thing you should do after you first setup WinMail and get it Working - is then make a copy of your 'Windows Mail' folder and save it just for these reasons below:
    ~If you update from Windows 8 to 8.1, or any version of 10, as well with many major MS updates that come along, they Will stop WinMail from working by overwriting many of the WM programs folder files and change folder permissions; but no problem, take ownership again and just replace the Windows Mail folder with your working one to bring it back to life.
    ~Also! ..if you run SFC /SCANNOW on Win8 or Win10 (not Win7 though) Will Break WinMail's operation each time you run it and will replace Many of the files within your Windows Mail folder. The way to fix it is very easy though, once again take ownership, and copy/paste your saved 'working' 'Windows Mail' folder replacing the one that's there.
    The point is after you perform the install procedure below and have WinMail working, then from there on after...
    ...Anytime any new MS Windows Updates or SFC /SCANNOW ..breaks WinMail can fix it in seconds simply by Taking Ownership of the Windows Mail folder again, and deleting the current Windows Mail folder replacing it with your saved 'working' backup one, and you're back in business.
    The above paragraphs are just previous time-line & informational conversation...

    How to install WinMail onto Windows 8 or 10

    (...first be sure in Folder Options these settings are set as shown in my screenshot Here)
    1. install Brinks Take Ownership.reg Here (is what I use, but see there's also Win8 & Win10 versions too)
    2. Then right click on your "Program Files/Windows Mail" folder* and click Take Ownership.
    * "Program Files/Windows Mail" folder only! ..x64 users don't touch the ''Programs Folder (x86)'' listing!
    * Also remember if your OS is x86 or x64 you cannot mix/substitute files from one into the other!
    3. Then right click on your "Program Files/Windows Mail" folder, and Delete it.
    4. Then copy/paste your saved 'working' Windows 7 (or Vista) 'Windows Mail' folder to Windows 8/10 same.
    5. Create a shortcut from the program folder 'WinMail.exe' file you just copied - to the Desktop.
    6. copy/paste your Windows 7 * ''C:\Windows\System32\msidcrl30.dll'' file over to Windows 8/10 same.
    7. Download the WinMailEdit.reg (supplied at the bottom of this post) ..and merge it (is for both x86 or x64)
    ~ Then you are done..
    ~ Start WinMail and she opens immediately..
    ...from here you setup the Windows Mail client as normal...

    Anyway, within minutes I had WinMail start up instantly in each of these OS's below.
    Here's the first run screenshots back on Win 8 beta CP, to Win 8.1, to all Windows 10 versions so far.
    Screenshots of WinMail on Win8 CP to Win 8.1 Pro & Win10 build 9841, 10041, 10162, 10240, 10586

    , and truthfully I agree with the warning article written at the WinMail on 7 thread, Please Read it!
    Basically using WinMail on 7, let alone using it on Windows 8 or especially Windows 10 - is Not Supported! ..and if used is a special per-user decision who Understands Completely what the article is saying!
    ..reactivating WinMail is for die-hard WinMail or expert users only! ...otherwise please move onward to more supported email clients! ...having said that, if you totally do get it, and can put up with the minor bugs, and importantly have the Technical Ability to make the changes, have backups of everything including your OS, and to be your own tech support for WinMail going forward - if you can do that, then like so many of us enjoy and much prefer using WinMail on Windows 7, 8, or 10 ..ymmv

    WinMail Bug List...are known issues from using WinMail within Windows 7/8/10 which will never be fixed.

    ~As of September 5, 2015 because of requests I've now supplied all necessary files needed for the WinMail transition available all in one place - attached at the bottom of this post.
    I'd prefer each person getting use to the experience of saving their own working x86 or x64 Windows Mail program folder files along with the msidcrl30.dll, and carrying it forward, however I realize sometimes people change from x86 to x64 OS's or lose their own copies, or never had it - and so these attachments below are now all here in one place for your convenience.

    ..and for heaven's sake, if this information has helped you please don't forget to 'log-in' to then be able to see and click the little 'thumbs-up' icon on the very bottom left of the post that helped you, this gives recognition to the poster and shows your appreciation for the considerable amount of work that's been done, I see it, and it is always greatly appreciated!
