    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 !!

    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)

    Advanced users can skip this section, and go on to the next..

    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 (and 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 which as of June, 2015 is 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 Win7 WinMail thread for its benefits, which makes WinMail more accurate for all the reasons discussed over the years within that forum; this same registry 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 needed WM programs folder files and change folder permissions; but no problem, take ownership of the Windows Mail folder again, and delete it, replacing it 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 since it also overwrites Many of the necessary files within your Windows Mail folder. The way to fix it is easy, once again take ownership of the Windows Mail folder, delete it, and copy/paste your saved working Windows Mail folder in its place.
    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 ...the first thing you do to have it fixed in seconds, is again simply Take Ownership of the Windows Mail programs folder, and delete it, replacing it with your saved 'working' backup one - and you're back in business; However also:
    Note: 4/2017 ..for Windows 10 users after performing new updates on b15063 and above:
    During repairs sometimes you also have to copy msidcrl30.dll to the System32 folder and merge WinMailEdit.reg again.

    * Important note: if you are doing a repair of WinMail because it will not start after an update, and you've been clicking WinMail.exe to get it to open but it won't.. ..then be sure to first reboot BEFORE you start the repair to clear any errant running instances of WinMail.exe; or instead of rebooting you can open Task Manager and end-task on all running instances of WinMail.exe, but in any case do it BEFORE you proceed to delete/replace the program folder.
    The above paragraphs are just previous time-line informational conversation...

    Advanced users start here:

    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 from Here (..or for Win10 Here, but registry lines are identical)
    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!
    * To clear any errant instances of WinMail.exe running - reboot BEFORE proceeding to do a repair.
    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, Server, and Win 10 up to build 16193
    Screenshots of WinMail on Win8 CP to Win 8.1 Pro & Win Server 2012 R2
    Screenshots of WinMail on Win10 build 9841, 10240, 10586, 14393, 15063, 16193, 16199, 16226 ...

    **Note: 6/2017
    Vista WinMail is no longer able to be reinstated on Windows 10 beyond version 1703 build 16193
    Microsoft has removed the OE legacy code of WinMail, see within article here:

    Features removed or deprecated in Windows 10

    Naturally Windows 8 and Windows 7 WinMail users are unaffected..


    , and truthfully I agree with the warning article written at the Win7 WinMail 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.

    ...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, it shows your appreciation for the considerable amount of work that's been done, and it's always greatly appreciated...
