Connection string error

[Philosophaie]

I am trying to connect to a Access database. I have setup in advance a Access db called "ToAccess.mdb".

In Visual Studio 2013 I have setup in web.config this excerpt:

<connectionStrings>
    <add name="Accessdb" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\User\Documents\a Access\ToAccess.mdb;Persist Security Info=False;" />  
</connectionStrings>

In Server Explorer>Data Connections>Add Connection... I selected Data Source:
Microsoft Access Database File (OLE DB)
I selected my Access file: "C:\Users\User\Documents\a Access\ToAccess.mdb" and it came up on my Server Explorer. That was ok.

I am having an error with my connection string:

"System.InvalidOperationException: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. ".

Any suggestions?

that has to do with your software and the machine it is installed on. are you stand alone or on a server ?

Sounds like your on a server and your machine does not recognize the MS access software that is on the server.

I have not put this db on my server. I am first learning how on my win8.1 Pro pc with localhost. It may be because I am working on Access 2016 Trial Version.

yes that is it because it says the DB software is not registered to your PC so you need to get your own software and load it on your machine
