Win32s with OLE Win32s is a subsystem created by Microsoft for the Windows 3.1x and Windows for Workgroups 3.1x 16-bit operating systems. The Win32s libraries allow Win3.1x and WfW 3.1x users to run Win32 (32-bit) applications on their 16-bit operating systems. Object Linking and Embedding (OLE) allows Mosaic to use its Common Client Interface (CCI) and communicate with other applications. Windows NT and Windows 95 Users: Windows NT v3.5 and Windows 95 are 32-bit operating systems with built-in support for OLE. WinNT and Win95 users should NOT install Win32s with OLE on their computers. The latest version of Win32s with the OLE libraries is version 1.25. It was released to address the National Language Support problem and the compobj.dll problem some Windows users were experiencing with Win32s v1.20. We recommend you upgrade to this latest version if you use a language other than English(American) in your Windows environment. We also recommend you upgrade if you have experienced problems with the compobj.dll library while using Microsoft Office, Excel or Word. In general, if you are NOT experiencing problems with Win32s v1.20, upgrading to Win32s v1.25 is not necessary. NOTE: Win32s Version 1.25 found on the Microsoft ftp server does not contain the OLE library extensions. You must use the version of Win32s we provide on this ftp server to get Win32s v1.25 with OLE.
