SYMPTOMS

When you install Office, you may receive the following error message

Internal Error 2343: Please contact product support for assistance.
followed by:
Installation ended prematurely because of an error.


CAUSE

When you uninstall Lotus Notes, the uninstall program does not remove certain entries in the Windows registry and the Win.ini file.

This problem only occurs if you have uninstalled Lotus Notes or if Lotus Notes is not installed correctly. Office installs successfully if the system has an intact installation of Lotus Notes that is installed correctly.


WORKAROUND

Microsoft has a utility to correct this problem. For more information about this utility, please see the following article in the Microsoft Knowledge Base:

If you choose not to use this utility, use either of these methods to resolve this problem.

Method 1: If Lotus Notes Is Not Installed

To modify the Win.ini, follow these steps:
  1. Click Start, and click Run. In the Run dialog box, type Win.ini.


  2. Click OK.

nsg=c:\notes\Notes.exe ^.nsg
nsh=c:\notes\Notes.exe ^.nsh
ns2=c:\notes\Notes.exe ^.ns2
ntf=c:\notes\Notes.exe ^.ntf
    NOTE: If Lotus Notes was installed to a folder different than the default (c:\notes), then these entries will reflect the path where Notes was installed.
