We've got SQL2005 April CTP i64 running on Win2003 with SP1 appied (Itenium Proc). Last week, one of developer sent me an email with error msg,
: Msg 7403, Level 16, State 1, Line 1
The OLE DB provider "Microsoft.Jet.OLEDB.4.0" has not been registered.
I ran Component Checker against that box and it found that MDAC2.8 with SP2 installed. I also found from MS site that Jet 4.0 SP8 i64 version available but the installation aborted due to newer version installed on the box. I am stucked. Any advice would be appreciated.

Microsoft.Jet.OLEDB.4.0 driver error on Win2003 SP1 & SQL2005 April CTP

If I remember correctly, the Jet OLE DB Provider is not included in MDAC 2.8. You can download and install the Jet OLE DB Provider from the following page:
http://msdn.microsoft.com/data/downloads/updates/default.aspx#jet
There is no 64 bit Jet OLE DB Provider. However, you should be able to access it from 32 bit applications.
I hope this information proves helpful.

So far there are no plans for a 64-bit Jet database engine driver.

Will a 64 bit Jet OLE DB Provider be available in the future
Thanks.

Reinstalling MDAC is not an option due to part of OS - Win2003 server. No option to upgrade either becuase of Windows SP1. The MDAC on that machine is the lasest and greastest.
Any other suggestion This is got to do with Mdac or Jet driver...a new bug on 64bit
