Known Issues in this Update

Symptom	Workaround
Applications that rely on a Microsoft Jet database using the Microsoft Access 97 file format may encounter issues if the database contains column names longer than 32 characters. In such cases, the database will not open and will display the error message: “Unrecognized Database Format.”	To resolve the issue, you can choose one of the following options: Option 1: Modify the database to ensure that all column names are 32 characters or less. This will ensure compatibility without needing to convert the database format. Option 2: Convert the database to the .accdb file format. After the conversion, you will need to update the connection string to reflect the new file format. The simplest method for conversion is to use Microsoft Access 2010 or earlier versions. These versions provide an easy way to convert older databases to the .accdb format.
