This problem is caused by the default security settings created when Internet Explorer 6 is installed.  Microsoft changed the settings in version 6 to disable a number of Outlook Express features by default.  These default settings are stricter than is necessary for full virus protection and have a side-effect of disabling most types of e-mail stationery.

There are two ways to fix this problem.  If you want to keep the maximum possible protection from viruses then you should use the first fix below.  If you want the same security settings as existed in previous releases of Outlook Express, use the second fix below.

1)    Maximum security fix:

Use the following setting to enable most stationery and to also have maximum security from HTML e-mail viruses.

Run Internet Explorer, click on Tools, then on Internet Options...  Next click on the Security tab in the "Internet Options" window.  Click on the Restricted Sites icon.  Under "Security level for this zone" click Custom Level.

In the "Security Settings" window which is displayed next, if the button labeled Reset is not grayed out, then we recommend starting by resetting the zone to its default settings.  To do this select  High in the "Reset to" box and then click the Reset button.  The Reset button should now be gray.

In the "Settings" box, scroll down to The "Active Scripting" entry, just under the "Scripting" heading.  Change "Active Scripting" to Enable.  Then click Ok, then Yes to confirm, then Ok to exit from the options window.

This change does not compromise security.  All viruses to date which have used HTML e-mail have used either attachments or loopholes in "ActiveX" security.   As far as we know, simple scripting cannot be used to transmit viruses and it is safe to re-enable it with this setting.

2)    Set security to medium:

Use this fix to set your e-mail security to the same level as existed before Outlook Express 6.  This fix works for stationery created with Scrippy, and also re-enables other types of stationery which use "ActiveX".

Run Outlook Express 6, click on Tools, and then on Options...  In the resulting "Options" window click on the Security tab, then under "Virus Protection", "Select the Internet Explorer security zone to use", select Internet Zone.  Click Ok to exit.

This setting does create some risk that a virus which is not known to your anti-virus program could invade your system.  (The risk is small if you run an anti-virus program and keep it up to date, but it is still possible.)" 

Those dll that you replace are different from the files needed after an
update has been done. I have attached the files needed, also in the zip is a
read me file which will tell you how and where to install them. Below is a
link that will also give you some info on it. I use this link all the time
when problems with stationery occur.
