Problem with .Net Framework 2 on certain machinesHi,
I'm trying to distribute my application written using .NET Framework 2.0. It uses a MDB file for it's database. On certain machines with Windows XP (I have also tried updating them to SP2), I received this exception when the application tries to connect to the MDB "The .Net Framework Data Providers require Microsoft Data Access Components (MDAC). Please install Microsoft Data Access Components (MDAC) version 2.6 or later." I have checked the machines using Component Checker Version 2.0 and has confirmed that the MDAC installed on the machine is already 2.8 SP1. Any help would be greatly appreciated. Hi,
Jet engine is a separate download (starting from MDAC 2.6 if I remember properly) thus you have to install it (just search ms website for it) separately. -- Show quoteMiha Markic [MVP C#] RightHand .NET consulting & development www.rthand.com Blog: http://cs.rthand.com/blogs/blog_with_righthand/ "Programatix" <N$SPAMprogramatixN0000@msn.com> wrote in message news:%23bKnUC5BGHA.2664@TK2MSFTNGP15.phx.gbl... > Hi, > > I'm trying to distribute my application written using .NET Framework 2.0. > It uses a MDB file for it's database. > > On certain machines with Windows XP (I have also tried updating them to > SP2), I received this exception when the application tries to connect to > the MDB > > "The .Net Framework Data Providers require Microsoft Data Access > Components (MDAC).

(http://www.microsoft.com/downloads/details.aspx?FamilyID=78cac895-efc2-4f8e-a9e0-3a1afbd5922e&displaylang=en): "This release does not include Microsoft Jet, the Microsoft Jet OLE DB Provider or ODBC driver, the Desktop Database ODBC Drivers, or the Visual FoxPro ODBC Driver." since MDB connection requires Ms Jet, you have to download (and install) it separately: http://msdn.microsoft.com/data/downloads/updates/default.aspx#jet I think this should solve your problem. Regards, Wiktor Zychla Sadly... it doesn't solve the problem.
By the way Microsoft Access XP is installed on those machines that have the problem. If Microsoft Access XP is already installed, then MS JET is already installed.

I am moving from VB6 to .NET and was hoping that all the installation problems associated with the use of Access 97 data bases would be solved. I was assuming that Framework 2 would include ALL NECESSARY components for the Data Access. I have a lot of existing problems with many installations including Windows XP Home and all can be traced back to the JET engine. OLEDB. I thought that all that was behind me. Obviously not Oh dear! Oh dear! Oh dear!

with the Service Packs for Windows XP. Eg, Windows XP SP2 comes with MDAC 2.8 SP1. The problem now is, on certain machines with all required components installed, .Net Framework 2.0 seems to be unable to detect them... or maybe giving out the wrong report during exception?

The Jet provider is not part of the recent MDACs. You would have to download a recent version of the provider which is not part of the MDAC downloads. Also try registering the latest version of the msjet*0.dll and see if that's the version the Framework picks. You can also use the "Process Explorer" to determine the version of the dll being referenced by your application. HTH! Skanda. Well... Ms Jet 4.0 SP8 is already installed and the problem is still there.
