XCLN: Setup Error: "Exchange Setup Was Interrupted..." (149230)

SYMPTOMS

When installing the Windows 3.x version of the Microsoft Exchange client, you may receive the following error:

Microsoft Exchange setup was interrupted before your new software was fully installed.

You can run Microsoft Exchange Setup in its entirety at a later time to complete the installation.

CAUSE

This error appears when you have another older version of Mapi.dll already installed on your computer that has a newer version stamp -- a version number newer then the one being installed by Microsoft Exchange.

For example, Novell GroupWise installs a pre-Exchange version of Mapi.dll that has a version stamp of 4.1. Before Exchange setup tries to copy Mapi.dll, it checks the version of the file. If the version of the previously installed file is newer than the one that setup is trying to install (4.0), the setup skips the file without copying it. This in turn causes the error.

RESOLUTION

To resolve the problem:

Delete the current Mapi.dll file from the Windows\System directory, and then re-run Microsoft Exchange setup.

To correct this problem on multiple workstations, modify the Exchang.inf file as outlined below.

Steps to Modify Exchang.inf File

Make a backup copy of your Exchang.inf file before proceeding.
Use Notepad to open the Exchang.inf file.

Find the following line in the [MAPI] section:

   "mapi.dll"=5,mapi.dll,,,,1996-03-11,,1033,,,,,,,,
      890464,SYSTEM,,,4.0.837.7,

The number preceding the last comma is the version number of the Mapi.dll file that is being installed. Change this number to be greater than the version number of the Mapi.dll file you already have installed. For example, if the currently installed file is version 4.1, change the line as follows:
```
   "mapi.dll"=5,mapi.dll,,,,1996-03-11,,1033,,,,,,,,
      890464,SYSTEM,,,4.1.0.1,
```
Save Exchang.inf as a text file.
Re-run setup.
