Updated version of Microsoft Jet 3.5 available for download

Warning To apply this service pack successfully, you need to have Microsoft Jet version 3.51.0623 or later installed on your computer. If your computer has an earlier version of Jet than this, you must upgrade your computer to Microsoft Office 97 Service Release 2 (SR-2). You can get information about Office 97 SR-2 and download the Office 97 SR-2 update from Tools on the Web at the following address: Failure to update your computer to the proper version of Jet may result in damage to your database products or may result in data corruption.


Note Jet35sp3.exe (Microsoft Jet 3.5 Service Pack 3) replaces Jet35sp2.exe (Microsoft Jet 3.5 Service Pack 2), which is referenced on the Microsoft Office 97 SR-2 pages on Tools on the Web (http://office.microsoft.com/). Service Pack 2 and Service Pack 3 are both Year 2000-compliant; however, Service Pack 3 also includes additional security updates that are not available in Service Pack 2. If you have not yet installed Service Pack 2 or Service Pack 3, you should install Service Pack 3.

The Jet35sp3.exe file contains an update of several .dll files that are included with Microsoft Access 97, Microsoft Office 97 Professional Edition, Microsoft Visual Basic version 5.0 or later, and other products that incorporate Jet 3.5x. Microsoft Jet database engine version 3.51 provides an improved Compact utility that combines Compact and Repair into a single process. Also, the updated version of the Jet database engine generates an error if it encounters a problem during the Compact process, and then creates the table, MSysCompactError, in the destination database.

Note Jetcomp.exe, which is included with Jet35sp3.exe, was updated on September 1, 1998. You can now use Jetcomp.exe on secured databases and databases that have a database password. Jet35sp3.exe now includes Jet 3.52 (MSjt4jlt.dll). Jet 3.52 only works with Jet's OLE DB provider and/or ADO going to Jet data via the Jet OLE DB provider. For additional information, see the following article in the Microsoft Knowledge Base:Note Jetcomp.exe is a stand-alone utility that allows you to compact databases created with Microsoft Jet database engine 3.x. This utility may be used in conjunction with Microsoft Jet database engine 3.51 for recovering corrupted databases. Although it is possible to use the Microsoft Access Compact utility or the CompactDatabase method with Microsoft Jet database engine 3.51, Jetcomp.exe may be able to recover some databases that these utilities could not. This is because the Microsoft Access Compact utility and the CompactDatabase method attempt to open and close a database before attempting to compact it. In certain cases where these utilities may not be able to reopen the database, Compact will be unable to proceed, preventing recovery of the database. Jetcomp.exe does not attempt to open and close the database before compacting, and may be able to recover some databases that the Microsoft Access compact utility and the CompactDatabase method could not.

The user interface of JetComp.exe is in English only and is not supported by Microsoft Product Support Services. However, JetComp.exe can be used to compact databases in any language supported by the Microsoft Jet database engine. Jetcomp.exe is a freely distributable utility, but requires that you have one of the following products installed:

• Microsoft Office 97
• Microsoft Access 97
• Microsoft Visual Basic 5.0
• A Microsoft Office Developer Edition 97 run-time application that includes the run-time version of Microsoft Access 97
• A Microsoft Visual Basic 5.0 run-time application that includes Microsoft Jet database engine 3.5
