OFFICE: 16-Bit Application Overwrites 32-Bit Libraries

ID: Q135098

The information in this article applies to:

SYMPTOMS

When you install a 16-bit Microsoft Office application, after installing a Windows NT version Office application under Microsoft Windows 95, the 32- bit libraries that Microsoft Excel and Microsoft Word use are overwritten by the 16-bit versions of these library files.

For example, when you run Microsoft Excel for Windows NT after installing Microsoft Excel version 5.0c for Windows, you receive the following error message:

An error occurred initializing the VBA libraries (-25346)


CAUSE

This problem occurs when you install a 32-bit Microsoft Office for Windows NT application, such as Microsoft Excel version 5.0 for Windows NT, and you then install a 16-bit Office application, such as Microsoft PowerPoint version 4.0 for Windows.

This problem occurs because Windows 95 does not have a System32 subdirectory like Windows NT does. When you install a 32-bit Microsoft Windows NT application, the applications library files are normally installed to the System32 subdirectory. If the System32 subdirectory does not exist, the files are installed to the System subdirectory. However, if you then install a 16-bit application, the library files for that application are installed to the System subdirectory, overwriting any 32- bit libraries that have the same name.
