“未在本地计算机上注册'Microsoft.ACE.oledb.12.0'提供程序的在线错误。”

Question

I am creating my website using my visual studio and Microsoft access as to create my database. in my local server and my own PC this web compile and run perfectly , but whenever I try to upload my web on the server and then run the part of my website that the web try to get access to the database I get the following error :

The 'Microsoft.ACE.oledb.12.0' provider is not registered on the local machine.

I've searched the internet and they all said it's because you are running on 64 bit windows and its' configs are for win 32 bit.

I have windows XP 32 bit and it works perfectly on my PC, but I think it's because of the servers local machines that are running on windows 64 bit (maybe). but the problem is I don't know what to do here. I don't know what to do. and all the internet solutions were for offline console programs, not the web services.

Answer 2

The simplest workaround is to change the Target Platform of your application through Visual Studio menu

In Project explorer:

 Solution (Right-Click) -> Configuration Manager -> Active Solution Platform -> x86

If the x86 option is not already there, then select NEW, name it x86 , Copy Settings from AnyCPU and check Create new project platforms
