I also don't know why in your connection string, I see a "/" forward slash? (why is this?). I used single quotes around the extended properties - so single or double will work. "Extended Properties='Excel 12.0 HDR=YES' " However, I find this works for either xls, and xlsx Dim strCon As String = "Provider=.12.0 " & It it is a pre xml format, then it is binary such as xls (as you have), then Extended Properties='Excel 12.0 HDR=YES' So, for xlsx format, you have to include the "xml" part: Extended Properties='Excel 12.0 Xml HDR=YES' Using M圜on As New OleDbConnection(strCon)ĭim daRead As New OleDbDataAdapter("select * from ", M圜on) "Extended Properties='Excel 12.0 Xml HDR=YES' " To open 2007 and later Excel files? Well keep in mind that Excel files save their data as xml (so do all offce documents - if you rename the xlsx extension as zip, you can now open any office document as a xml file)Īnyway, the connection string will look like this for REAL 2007 format files (and later - note the use of xml tag) Dim rstData As New DataTableĭim strCon As String = "Provider=.12.0 " &

The above zip file has two samples - run them both and you know what version of ACE you have installed and working. If ACE works, then you can try your connection string to Excel, but you need to ensure that ACE 圆4 is working. The inter-op does not provide use of office, only a set of references for your convenience. You don't need (nor does it help) to use the office interop assemblies, since you using the ACE provider for this. The working x32 and 圆4 with a file browse to test ACE is here: You need to first test + check if ACE is working. If that works THEN try connecting to Excel. FIRST test if you can browse and open a accDB file.
#Microsoft access database engine 2016 .exe
exe (one is x32 and one is 圆4) that you can try and see if ACE is working.

I would test if ACE is installed and working. 12 for the ACE version should work from versions 2010 all the way up to 2019 without having to change the provider string.
#Microsoft access database engine 2016 install
In addition to having to install ACE separate now (in most cases), you find that using. It also much smaller then the whole run-time, and thus that's a bonus if you actually don't need Access run-time, but just need ACE. For 2016, it quite much always the case (ACE not exposed).

So the later versions of office (staring around 2013) will not install + expose ACE anymore. net project running as 圆4, and that will not work with Access (or ACE) x32.Īlso, last but not least, while your ACE.15 reference worked, to my knowledge for all the installs (Access 2010, 2013, 2016 and now 2019) ? You as a general rule should find that Provider=.12.0 Data Source=C:\test3\test44.accdb net project to x86, since if you choose "any" or 圆4, then you in most cases result in your. net project to x32 (and if you ARE intending to use x32 bits, then you MUST MUST force your. Make sure you grab the x32 bit version if you are forcing your. So, you have to install the ACE data engine separate now. And as noted for C2R installs of Access (or the run-time), you will find that ACE is not exposed and registered anyway. Prior to 2016 (and in fact for some 2013 Access installs), installing access run-time = ACE data engine installed and registered on your computer.Īs a result of the above, if you don't really need to launch and automate Access, then ONLY install the ACE data engine. What this means is that now when you install the Access 2016 runtime, it does not expose an instance of the ACE database engine.Īs a result, you actually don't need (or even want) to install the whole big run-time to JUST get use of the ACE database engine. Due to the changes in the Access runtime and office Click to run installs? Well all of office now typical runs as a virtualized application.
