Hello,

I am developing a contact application on Visual Studio 2019. When I pressed the "Start" button, I was unpleasantly surprised to see that my application did not launch and that this text appeared 
System.InvalidOperationException: 'The provider 'Microsoft.Jet.OLEDB.4.0' is not registered on the local machine.'


I then went to look online and did what the vast majority of forums suggested: Install Microsoft.Jet.OLEDB.12.0, but that did not work. Thank you for your help.

From memory, this error may appear if you compile in AnyCPU or x64, try forcing the compilation to x86 (32 bits).

I mainly work in VB6 and VB.NET, with a bit of C#, but moderation often brings me to other languages.
In VB.NET, remember to enable "Option Explicit" and "Option Strict".

Thank you for your response, but since I am a novice, could you explain to me how to force the compilation in x86???

I don't have an IDE on this PC, but I think the method should be similar:
