After Assigning new project to 64 bit in Configuration Manager, configuration was unsuccessful

Question

I built a new project and imported all the forms and codes from the previous project. In the menu Build, I assigned 64 bit in the Configuration Manager, and it's showing in the ribbon that the project is 64-bit.
However, when the codes run

If IntPtr.Size = 4 Then 'access

    ElseIf IntPtr.Size = 8 Then 'or sql

    End If

It is automatically selecting the IntPtr.Size=4, which proves that the project is still 32 bit.
How can I correct this problem?

Hi @Simon ,

Welcome to Microsoft Q&A!

Please uncheck the “Prefer 32-bit” by right-click on project properties > Build. Then, try again.

Sincerely,
Anna
