Windows Calendar and Windows Mail for Microsoft® Windows 7

Prerequisites for Windows Calendar
Prerequisites for Windows Mail


The setup scripts WINCAL.INF and WINMAIL.INF install and enable the application Windows Calendar and enable the application Windows Mail on Microsoft Windows 7, using (some of their) files from Windows Vista® or Windows Server 2008.

Note: Windows Calendar and Windows Mail are part of the Desktop Experience feature of Windows Server 2008 and thus serviced with security updates as long as Windows Server 2008 R2 and Windows 7.


Although Windows Mail, the successor of Outlook Express alias Microsoft Internet Mail & News, and almost all of its components are shipped with Windows 7, it does not start with a visible window any more.
The MSDN article Removal of Windows Mail provides some details.

Windows Mail references Windows Calendar, which is but not shipped with Windows 7 any more.


The setup script WINMAIL.INF replaces the file MSOE.DLL with the one supplied to it, creates a shortcut Windows Mail in the start panel and adds the missing Registry entries to enable Windows Mail on Windows 7.

Caveat: installation of the security update MS10-030 alias 978542 or running the System File Checker after the setup script WINMAIL.INF will replace MSOE.DLL with its current version from Windows 7.
Just rerun the setup script WINMAIL.INF to undo this damage!

The setup script WINCAL.INF copies the supplied files, creates a shortcut Windows Calendar in the start panel and adds the missing Registry entries to install and enable Windows Calendar on Windows 7.


An (original) installation DVD of Windows Vista or Windows Server 2008 for the language(s) and processor architecture(s) of the target installation of Windows 7.

Prerequisites for Windows Calendar

for the I386 alias x86 processor architecture from the Service Pack 2 for Windows Vista or Windows Server 2008;
for the AMD64 alias x64 processor architecture from the Service Pack 1 for Windows Vista or from the installation disc of Windows Server 2008.
from the installation disc of Windows Vista or Windows Server 2008.

Prerequisites for Windows Mail

from the security update MS10-030 alias 978542 for Windows Vista or Windows Server 2008.


Perform the following 5 steps to create the installation source.
  1. Create an empty directory.
  2. Create the subdirectories I386\ and AMD64\ in the empty directory created in step 1.
  3. For every locale alias language and culture you need or want to support and have the language file WinCal.exe.mui, create a subdirectory ‹locale›\ using the ISO language and country codes, i.e. en-US\, de-DE\, … etc. in both subdirectories created in step 2.
  4. Copy the files listed as prerequisites into their appropriate subdirectories.
  5. Copy the setup scripts WINCAL.INF and WINMAIL.INF into the directory created in step 1.


The setup script WINCAL.INF installs the language file(s) only for the locale active during the installation!


Installation requires administrative privileges and access rights.

In the directory created and prepared above, right-click the setup script WINCAL.INF or WINMAIL.INF respectively to display its context menu and click Install to run the installation.

Note: InfDefaultInstall.exe, the application registered for the Install verb of *.inf files, requests administrative privileges.

Note: on systems with AMD64 alias x64 processor architecture, the installation must be run in the native (64-bit) execution environment!


The setup scripts support the update from any previous version: just install the current version!

Use the X.509 certificate to send S/MIME encrypted mail.

Note: email in weird format and without a proper sender name is likely to be discarded!

I dislike HTML (and even weirder formats too) in email, I prefer to receive plain text.
I also expect to see your full (real) name as sender, not your nickname.
I abhor top posts and expect inline quotes in replies.
