SYMPTOMS
When you install Outlook 98 with the Outlook Deployment Kit (ODK) over a client that has Internet Explorer 5 installed, or Internet Explorer 4.0 Service Pack 2 (SP2) already installed with IEAK, the installation fails and the following error message is generated:
NOTE: If the ODK package is set to install in silent mode, no error message is displayed, and Setup simply exits.
CAUSE
This will occur if the following conditions are true:
- Internet Explorer 5 is installed on your system. - and -
- You deploy Outlook 98 using the ODK. - and -
- Your binary cabinet (CAB) files have not been signed as explained in the ODK Documentation.
- Branding.cab
- Desktop.cab
- Outlcif.cab
- Setup.exe
- Folderx.cab
- Chlxxxx.cab
This problem can also been seen when Internet Explorer 4.0 SP2 is deployed using IEAK.
If your operating system is Windows 98 and you have been to the windowsupdate.microsoft.com Web site, it downloads the latest version of Wintrust.dll, which gives this error.
RESOLUTION
To resolve this issue, sign your Outlook 98 binary cabinet files:
- Branding.cab
- Desktop.cab
- Outlcif.cab
- Setup.exe
- Folderx.cab
- Chlxxxx.cab
WORKAROUND
To work around this issue, change the "Local Intranet Zone" security zone of Internet Explorer 5 or Internet Explorer 4.0 SP2 so that unsigned files can be executed. Here is the registry key you can import to make this change programmatically:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\1\1004
Set this RegDWord to 0 (Zero).
Here is the explanation for the registry key value:
dword:00000000 : Enabling Unsigned Files download
dword:00000003 : Disabling Unsigned Files download
dword:00000001 : Prompting for Unsigned Files download
You can also rename Wintrust.dll, install Outlook 98 using the ODK, and rename the Wintrust.dll back.
