The is for the Itanium 64 bit, not the AMD or the Intel 64 bit. To my
knowledge (but I might be wrong) there won't be any 64 bit driver for JET;
probably because of security concerns.
In my opinion: either for the 32 or the 64 bit environment, it's usually a
bad idea to use a MDB file as your backend database when you could use
SQL-Server Express instead; even when this database has been first created
with Access. With its poor performance over a network, lack of security and
of fiability, the use of the MDB file format as the backend should only be
used inside a strictly confined Access environment, nothing else and even
then, the use of ODBC linked tables against a SQL-Server is probably a
better and safer option.
The fact that there is no 64 bit driver for JET at this moment and that
probably there will never be one should ring a little bell inside your ears.
See this as a wake up call.

I've heard conflicting reports. You might want to try asking the Access
experts in one of the Access groups.
Wait, I just did a google search and this came up:

This only seems to be useful if you are using Windows Server.

Tank for you answer.
I understand that I can't use jet with 64 bits build.
Just one more question: do you know if Microsoft will develop a 64
bit jet drivers? if yes when can you expect have it? if no what
solution for read mdb data file with a 64 bit build software?
Thank.

Hello,
I am using CRecordset foe acces .mdb file created with ms acces.
if I build my softwre on 32 bits all is fine
but when I make a 64 bit build I have a message who say that system
can't find data. In French message:
"Source de données introuvale et nom de pilote non spécifié".
What is the problem ? and how can I do.
Does anyone have an idea on this?
thanks in advance for the help
Christophe
You are out of luck. There is no 64-bit provider for Jet.
In order for IIS to use 32-bit drivers, you must flip it from 64-bit
to 32-bit.
