Issues that are fixed in this update rollup

The following issues are fixed in this update rollup but were not previously documented in a Microsoft Knowledge Base article:

•	On a Microsoft Windows Vista-based computer, you run programs that use the Microsoft Jet Database Engine. When you synchronize a database over the Internet, you may receive the following error message: Assertion failed! Program: … File: ..\COMMON\inc\safestrfuncs.h Line: … Expression: S_OK ==hr For information on how your program can cause and assertion failure, see the Visual C++ documentation on asserts (Press Retry to debug the application – JIT must be enabled) Additionally, if you click Abort or Retry, Microsoft Office Access closes. If you click Ignore, the same message appears repeatedly until the synchronization is complete. Note The "Assertion failed" error message may also appear outside database replication scenarios.
•	When you use the DAO Seek method on a Windows Vista-based computer, the function may not find a record that matches the criteria. This may occur even though there are matching values in the record set. You may experience this issue only if the following conditions are true: • The database that is queried is in Access 97 format. • The Windows system locale (language) is set to a language other than English. • The indexed column contains double-byte character set (DBCS) data. • The column and index were created by using the DAO Tabledefs method and not by using the SQL CREATE TABLE statement or the SQL CREATE INDEX statement. • A compaction or a repair of the database has not been performed since the column was created.
•	When you use a Jet 4.0 database that has links to an ODBC SQL database, you may receive an error message that resembles the following: Access has encountered a problem and needs to close. We are sorry for the inconvenience. If you were in the middle of something, the information you were working on might be lost. Please tell Microsoft about this problem. We have created an error report that you can send to help us improve Access. We will treat this report as confidential and anonymous. To see what data this error report contains, click here. When you view the data that the error report contains, you see information about common error signatures. This information resembles the following: Application name Application version Module name Module version Offset Msaccess.exe 11.0.6566.0 Msjet40.dll 4.0.9635.0 Offset_Value This information may vary depending on the version of Access that you are running. The information may also vary depending on the program that you use as the front end for the Jet 4.0 database engine.
•	When you use Internet Explorer or Access, you may receive an error message that resembles the following: Application_Name has encountered a problem and needs to close. We are sorry for the inconvenience. If you were in the middle of something, the information you were working on might be lost. Please tell Microsoft about this problem. We have created an error report that you can send to help us improve Application_Name. We will treat this report as confidential and anonymous.
