SUMMARY

WARNING: This service pack cannot be used with Microsoft Jet 4.0 version 2115.25 that shipped with SQL Server 7.0. Users with this version of Jet must upgrade to SQL Server SP1 or MDAC 2.1.2.4202.3 (GA) before applying this service pack. Failure to do so will likely break your database products and could cause data corruption.

Users with Microsoft Jet 4.0 version 2521.09 or version 2808.00 are advised to upgrade to MDAC 2.1.2.4202.3 (GA) before applying this service pack to ensure consistency of the database components on their computers. For more information about, and to download MDAC 2.1.2.4202.3 (GA), please visit the following Microsoft Web site:

The Jet40SP3.exe file contains an update of several .dll files that are included with Microsoft Access 2000, Microsoft Office 2000 Developer, Microsoft Visual Basic version 6.0 or later, and other products that incorporate Microsoft Jet database engine 4.x. Version 4.0 SP3 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 is a stand-alone utility that allows you to compact databases created with Microsoft Jet database engine 4.x. This utility may be used in conjunction with Microsoft Jet database engine 4.0 for recovering corrupted databases. Although it is possible to use the Microsoft Access Compact utility or the CompactDatabase method with Microsoft Jet database engine 4.0, 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 2000
Microsoft Access 2000
Microsoft Visual Basic 6.0
A Microsoft Office Developer 2000 run-time application that includes the run-time version of Microsoft Access 2000
A Microsoft Visual Basic 6.0 run-time application that includes Microsoft Jet database engine 4.0
