I've got a 32 bit .net 2.0 app that uses the Jet OLEDB 4.0.
Active3 years, 1 month ago
It runs fin on Windows 8 32 bit, but not on the 64 bit. on 64 bit I'm getting an error:
OLE DB is a Microsoft data access standard accessed through ActiveX Data Objects (ADO), Visual C, and any client that can use OLE DB. The goal of the Oracle Provider for OLE DB is to have a high performance and rich feature mechanism for data access to Oracle databases The Oracle Provider for OLE. May 14, 2019 Microsoft OLE DB Driver 18 for SQL Server is a single dynamic-link library (DLL) containing run-time support for applications using native-code APIs to connect to Microsoft SQL Server 2012, SQL Server 2014, SQL Server 2016, SQL Server 2017, Analytics Platform System, Azure SQL Database and Azure SQL Data Warehouse. Sep 04, 2019 I just got a new computer (I went from Windows Vista to Windows 7). When I create the UDL file to connect to my Access database, I no longer have the option for the provider 'Microsoft Office 12.0 Access Database Engine OLE DB provider'.
'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine. at System.Data.OleDb.OleDbServicesWrapper.GetDataSource(OleDbConnectionString constr, DataSourceWrapper& datasrcWrapper)
I am aware that you can't use that database (driver) with a 64 bit EXE. However I've not read anything about it not working with the 32 bit exe.

Problem is, I can't find any place to download it.

On modern Windows this driver isn't available by default anymore, but you can download as Microsoft Access Database Engine 2010 Redistributable on the MS site. If your app is 32 bits be sure to download and install the 32 bits variant because to my knowledge the 32 and 64 bit variant cannot coexist.

Depending on how your app locates its db driver, that might be all that's needed. However, if you use an UDL file there's one extra step - you need to edit that file. Unfortunately, on a 64bits machine the wizard used to edit UDL files is 64 bits by default, it won't see the JET driver and just slap whatever driver it finds first in the UDL file. There are 2 ways to solve this issue:
[oledb] ; Everything after this line is an OLE DB initstring Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:PathToThedatabase.mdb;Persist Security Info=False
