Our company has an existing application (standalone PC app) that uses Access database via the Jet Engine. The program runs on a user’s machine only (distributed from a CD or USB jump drive.). We are looking to convert this application to .NET, keeping in mind that we need to have an easy setup with a royalty free solution.
< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
Should we continue to use the Jet Engine or is it time to upgrade to MSDE Is the Jet Engine being phased out. The new application has to be able to work with the older database.

upgrade to MSDE

Microsoft Access is not being phased out and will co-exist. If you do not have any issues with the existing Access database then you could remain with it.
You can consider the new SQL Server 2005 Express database also.
