However, as is the case with other spreadsheet and database programs, Quattro Pro and Paradox (which is included with some versions of this product), may have some date usage issues which can result in Y2K problems. For a summary of Y2K issues which may affect spreadsheets and databases, see Data Files: Finding & Resolving Y2K Problems .

• Corel WordPerfect Office 2000 is stated by its vendor to be Y2K compliant.
  
  
• Corel WordPerfect Suite 8 is stated by its vendor to be Y2K compliant.
  
  
• Corel WordPerfect Suite 7 is stated to be compliant with "minor issues." .
  
  For instance, the vendor describes some minor Y2K issues in Quattro Pro 7 which relate to Date Entry, Date Display, and the Data Modeling Desktop feature, and issues in WordPerfect 7 which relate to the use of date assumptions in the Document Summary feature and in Tables.

• Microsoft Internet Explorer for Windows 5.0 is asserted by Microsoft in its Y2K Product Summary for Internet Explorer for Windows to be Y2K compliant.
  
  As mentioned in the above Product Summary, Internet Explorer 5.0 may incorrectly display years later than 1999 if an older version of a particular Microsoft library file (MFC40.DLL) is installed. To avoid this problem, install Microsoft's Y2K-related operating system updates to Windows 95, 98, or NT, which you can locate via the Platform-Specific Y2K Readiness Checklists page.
  
  
• Microsoft Internet Explorer for Windows 4.0x needs to be updated to version 4.01 Service Pack 2 or upgraded to version 5.0 for Y2K compliance. For details regarding its Y2K issues and available updates and upgrades, see the discussion of how to resolve minor Y2K issues in earlier versions of Microsoft's Web browser, Internet Explorer .
  
  
• Microsoft Internet Explorer for Windows 3.0x should ideally be upgraded to either version 4.01 Service Pack 2 or to version 5.0 for Y2K compliance. For details regarding its Y2K issues and available upgrades, see the discussion of how to resolve minor Y2K issues in earlier versions of Microsoft's Web browser, Internet Explorer .
  
  As an alternative, one can apply three individual updates, which are described in Microsoft's Y2K Product Summary for Internet Explorer for Windows 3.XX .
  
  
• Microsoft Internet Explorer for Macintosh versions 4.0a, 4.01 and 4.5 are asserted by Microsoft to be Y2K compliant:
  
  Y2K Product Summary for Internet Explorer for Macintosh 4.5
  Y2K Product Summary for Internet Explorer for Macintosh 4.01
  Y2K Product Summary for Internet Explorer for Macintosh 4.0a

  Connections to certain secure Web sites using Internet Explorer for the Macintosh may display an error message beginning January 1, 2000

  When you use Internet Explorer for the Macintosh versions 4.5 or 4.01 (and potentially earlier versions, as well), to connect to certain secure Web sites on or after January 1, 2000, you may encounter a dialog containing the following error message:
  

  Unable to establish a secure connection to "<site>." There is a problem with the security certificate from that site (The identity certificate has expired.)

  For a detailed description of this problem and how to resolve it, see Some Web Browsers Will Display Security Certificate Error Messages After December 31, 1999
  
  
• Microsoft Internet Explorer for Macintosh version 3.0x is asserted by Microsoft to be non-compliant due to problems in JavaScript's handling of two-digit-year dates such as "00" and "01" and non-expiration of ratings after 1999, as described in the vendor's Y2K Product Summary for Internet Explorer for Macintosh 3.XX

However, several of the individual Microsoft Office application programs, most notably Microsoft Excel and Microsoft Access (the latter is included in some Windows versions of Office), have some date usage issues which can result in Y2K problems. Make sure that anyone using the product is fully aware of these usage issues.

For details, see Microsoft's Y2K Product Summaries for the individual Office products via Microsoft's Year 2000 Product Guide , as well as the summary of Y2K issues which may affect spreadsheets and database files - including those created or modified by Excel and Access - which you can find in Data Files: Finding & Resolving Y2K Problems .

• Microsoft Office 2000 for Windows is asserted by Microsoft in its Y2K Product Summary for Office 2000 Standard for Windows to be Y2K compliant.
  
  However, as noted above, there are some Y2K date usage issues which can affect individual applications such as Microsoft Excel and Microsoft Access, both in Office 2000 and in all previous versions of Office.
  
  
• Microsoft Office 97 for Windows requires the Office 97 SR-2b update for Y2K compliance. This sizeable update can be downloaded or obtained on CD (recommended) at no cost.
  
  Microsoft describes nearly all of the Y2K fixes included in this update in the Support Online article Year 2000 Related Problems Corrected in Microsoft Office 97 SR-2 . (The SR-2b update also incorporates two additional Year 2000 updates for Outlook and Microsoft Jet 3.5, whose descriptions are linked from the Office 97 SR-2b update page.)
  
  Microsoft states that to install SR-2b, you must [first] have Office 97 Service Release 1 (SR-1) or higher installed on your computer. The Office 97 SR-1 update can also be downloaded or obtained on CD at no cost.
  
  For help in determining which Office 97 Service Releases have already been installed, you can download and run Microsoft's Office 97 Version Checker .
  
  
• Microsoft Office 95 for Windows requires the Office 95 Year 2000 Update for Y2K compliance, which can be downloaded at no cost. See Microsoft's Support Online article How to Download and Install the Year 2000 Update for detailed instructions. This article notes that:
  
  There have been several releases of this patch. If you downloaded this patch prior to July 1999, you may want to download it again and reinstall it to ensure that you are using the most current version of the patch.
  
  
• Microsoft Office 98 Macintosh Edition is Y2K compliant, according to Microsoft, when we last checked the vendor's Readiness Disclosure on January 4, 2000.
  
  However, in late December 1999, Microsoft released an update to Microsoft Excel 98 that corrects a problem when saving worksheet data to text files using Visual Basic for Applications. This problem results in dates being saved with only century-ambiguous two-digit years, which can cause these dates to be assigned to an incorrect century when later imported by Excel or another program. The update is available in two formats: as a standalone Microsoft Excel 98 Y2K Updater and included with other Office 98 fixes in a Microsoft Office 98 Macintosh Edition/Mac OS 9 Updater .
  
  In addition, Microsoft has for some time made available a no-cost patch to resolve a minor issue when saving files from PowerPoint 98 for use with PowerPoint 4.0.
  
  
• Microsoft Office 4.2.1 for the Mac OS is stated by Microsoft to be compliant with some very "minor issues" affecting some of the individual Office applications. There is no patch or update available to resolve these minor issues.

Connections to certain secure Web sites using Netscape browser versions 4.05 and earlier may generate error messages beginning January 1, 2000
