回答1:

Are you running 64 Bit? Here's the latest drivers which supports it:

It took MS forever to get 64 Bit drivers for Jet 4.0.

回答2:

I solved this by going to project properties | Build, and changing Platform Target to x86.

回答3:

If it's the 32 bit windows, and it worked previously, maybe right click mdac.inf in c:\windows\inf and choose Install to reinstall/repair it. It may ask for your windows cd.

回答4:

try

regsvr32 /u Msjet40.dll

regsvr32 Msjet40.dll

回答5:

Yes, one way it can be resolved by making the value of the property Run64BitRuntime to be false in project property.

SQL Server 2012 SSIS Excel import fail issue due to OLE Jet driver

SSIS project fails to build due to OLE Jet drive 64 bit version and you get the following error:

Microsoft.Jet.OLEDB.4.0 is not registered

Here is what you can do:

Right click on your SSIS project name and choose properties, go to:

Configuration Properties -> Debugging tab. (expand Configuration Properties if you do to see Debugging right way).

Make the value of the property Run64BitRuntime to be false.
