How to fix the "Microsoft.Jet.OLEDB.4.0 provider is registered" error? VB.Net Code for beginners

This error generally pup up with Window-7  of 64 bit version not with 32 bit because:

• Microsoft Access database provider(the Microsoft.Jet.OLEDB.4.0 provider) is not available in a 64 version- it is only available as 32- bit.
• Generate the " Microsoft.Jet .OLEDB.4.0 provider is not registered on local machine" error when attempting to load a form that connects to database.

For fixing this error depends o whether you are running Visual Studio Ultimate Edition or the Visual Basic Express Edition.

For Visual Basic Ultimate Edition Fix: In order to connect to an Access database when running Visual Studio on a 64-bit machine, you need to specify for Visual Studio to use 32-bit mode.Follow following steps

• 1.   Open Solution Explorer -- click on the My  Project node to the My Project

• 2.   Click the Compile tab along the left side of My Project --shown below will display.

• 3.   Click the Advanced  Compile  Options... button tothe Advanced Compiler Settings dialog box.
• 4.   Click the Target CPU drop-down arrow and select the x86 target --this will allow your program to run in 32-bit mode.

For Visual Basic Express Edition Fix: Use this procedure if you are running Visual Basic Express Edition. In order to connect to an Access database when running Visual Studio on a 64-bit machine, you need to specify for Visual Studio to use 32-bit mode; however, the above procedure will not work because the Advanced Compiler Settings window will not display a Target CPU drop-down box. Instead, you will need to carefully modify the project file using a text or XML editor.

• 4.   After opening the file, it should display (open) in an XML editor window.
• 5.   Locate the first <PropertyGroup> section and add the following

<PlatformTarget>x86</PlatformTarget>
