I had install a Visual studio 2013 ultimate version and oracle 11g express edition (11.2.0.2.0 64 bit) in my pc.
I tried to open a existing project and try to connect the database, but it throw me the error above. as long as I refresh the database OR conn.open(), it will throw me "OraOLEDB.Oracle provider is not registered on the local machine".
Anyone has experience this issues? or any method that might help on this? I have struggle with this problem for few days.
Your comment and suggestion is much appreciated!!!
Looks like you did not install the "OraOLEDB.Oracle" - it is not included by default.
Check your options in Oracle Universal Installer or you can download it from here 64-bit Oracle Data Access Components (ODAC) Downloads
Note, since you installed 64 bit version of Oracle, you also have to compile your application as "x64", otherwise it does not work.

'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. I am getting this in visual studio only after upgrading from 32bit office 2013 to 64bit office 16. I have already installed the 64bit database engine and my published project from IIS is working with the existing access database. I switched debug mode to x64 and remove the references to the old office and replaced them with the new office access. How can I get Visual Studio 2010 to recognize my access database created in access 2013?
Things I have tried:
Installing Microsoft Access Database Engine 2010 Redistributable 64bit version.
Updating the office references in the project.
Debugging in x64 mode
This is a little outside of my normal area of database application design;
it's unclear - you state 2016 Office 64 bit installed but then Access 2010 Redistributable/Runtime 64bit - - so do you have a full license of Access installed?
if you do have the full Access license - try something that is quick: create a brand new database and import that table. Then try the link to this new db.
I had that issue in the past.
install 2007 Office System Driver and restart visual studio.
I've dealt many time with this problem, the solution was ever install one of these:
AccessDatabaseEngine 2007.exe
AccessDatabaseEngine_2010.exe
AccessDatabaseEngine_2016.exe
AccessDatabaseEngine_X64_2010.exe
AccessDatabaseEngine_X64_2016.exe
Most of the time I've solved installing the 2007 one even using 2016 version.
To run 32-bit applications on IIS, you will get the same error. So, from the IIS 7, right-click on the applications' application pool and go to "advanced settings" and change "Enable 32-Bit Applications" to "TRUE".
Restart your website and it should work.
I am trying to install the correct Oracle drivers on my development machine. I'm creating an ASP.NET web site and every time I run I get an error saying that says "The provider is not compatible with the version of Oracle client". I have tried both 32-bit and 64-bit Oracle drivers but have still had no luck. Can someone lead me to a link for the drivers I need based on my specs?
I'm using Windows 8 64-bit. The database is Oracle 11.2.0.2.0 - 64 bit.
The ODAC112021Xcopy_x64.zip might give you the dll's and client you'll need. Take a look at this previous answer for more detail about deployment of the application.
I have installed Microsoft Access Database Engine 2010 Redistributable http://www.microsoft.com/en-us/download/details.aspx?id=13255 on the Windows 2008 server. However, when I ran my web application to import a spreadsheet table to the database. It complains with the error message - "Microsoft.ACE.OLEDB.12.0 is not registered in the local machine."
I have tested my code and works in my Windows 7 local machine. Any idea?
There is a problem with Microsoft.ACE.OLEDB.12 when AccessDatabaseEngine x86 or x64 2010 is installed.
I have long attempted to use the SSMS (2005-2008-2008R2-2012) Export Wizards to export large tables onto Excel and I needed the AccessDatabaseEngine installed to be able to do that.
However, regardless of the MS Office version (2010, x86 or x64, or whatever it is), the 2010 version of AccessDatabaseEngine will not work towards registering the provider.
The solution is to download and install the previous one which is none other than the 2007 x86 one.
This one will work even if Office or SQL Server or VS are x64.
Download it from here http://www.microsoft.com/en-us/download/confirmation.aspx?id=23734
Now, any other propagated issues revolving around the notorious failure to register "the provider" on the local machine for the Microsoft.ACE.OLEDB.12 should be resolved by the above.
Feel free to paste me your experiences on this matter.
I have a new development machine Windows 7 x64 and am writing an MVC3 application that targets an Oracle database. I have tried everything that I know of to get it running with no success.
Previously, I was developing on a Win7 x32 box and could debug fine locally, but was unable to deploy and run it on a Win2008 x64 Server despite having ODP.Net and 11g Client installed.
"Could not load file or assembly 'Oracle.DataAccess' or one of its
dependencies. An attempt was made to load a program with an incorrect
format"
On my new x64 machine, I can build the project but when i try to run it in via the IDE I get:
"The provider is not compatible with the version of Oracle client"
I am at a complete loss.
Does anyone have a similar setup that could share detailed instructions of what to install where and how to to reference Oracle.DataAccess in such a way that I can debug in the IDE on my x64 box, and also deploy to x64 server?
It should not have to be this difficult.
I do have this running on Windows 7x64 with the Oracle 11g R2 client that comes with the ODAC installation here:
http://www.oracle.com/technetwork/topics/dotnet/index-085163.html
Make sure you have the x64 version installed locally, and you may have to do the uninstall-reboot-reinstall-reboot tango. I also had weird problems getting it to see TNSNAMES entries and had to go with EZCONNECT strings, but that's not your problem.
In fact, I've also gotten it working on x64 using the 32 bit EF beta and it works fine:
http://www.oracle.com/technetwork/topics/dotnet/downloads/oracleefbeta-302521.html
Although I don't think the EF implementatinon is 100% ready for prime time yet (we ended up using the DevArt driver instead because it had more reliable support for computed fields - we never did get Computed or Identity Timestamps working in ODP.NET EF Beta, although oddly Primary Key NUMBER fields populated by triggers did work.)
I didn't have to do anything special, and I didn't have to do anything special on the server side either (with both 10g and 11gR2).
So I finally figured it out. Here is what I did step-by-step:
On my Win7 x64 development machine I removed all Oracle products in an attempt to start from scratch (including manually deleting registry keys and files/folders)
I installed "Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64) " ON BOTH the dev machine and production IIS server
I selected the RUNTIME option for the installation
During my first attempt the installation complained of not enough room in the PATH
environment variable so I had to cancel the install, remove some path values (which a replaced after the install completed
I installed to C:\oracle was my base path and client_x64 was my HOME so it installed to C:\oracle\product\11.2.0\client_x64
I then installed "64-bit ODAC 11.2 Release 3 (11.2.0.2.1) for Windows x64" on BOTH the dev and production mahcines.
install.bat odp.net4 c:\oracle\odac11.2.x64 odac112x64
The above statement creates a new home named odac112x64
At this point I built a simple console app using the following setup
Added reference to Oracle.DataAccess.dll located in C:\oracle\odac11.2.x64\odp.net\bin\4
Set CopyLocal = FALSE for the Oracle.DataAccess reference
Set the application to build for "ANY PROCESSOR"
The app connected to my oracle database and returned records on both machines
I then created a sample MVC website project with the same connection code as the console app.
When I ran it locally in the IDE it threw an error:
"Could not load file or assembly 'Oracle.DataAccess,
Version=4.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342'
or one of its dependencies. The system cannot find the file specified."
I believe this is because the IDE is 32bit and could not load a 64bit Oracle.DataAccess
I published that exact code to the production server and it ran successfully
At this point my only problem is getting it to run locally for development purposes
I installed "ODAC 11.2 Release 3 (11.2.0.2.1) with Xcopy Deployment" which is the x32 version of ODP.NET
install.bat odp.net4 c:\oracle\odac11.2.x32 odac112x32
When I re-ran the MVC website project locally it worked as expected!
UPDATED FOLLOW-UP INFORMATION #1:
After getting this to work I attempted to apply the same steps to another server and it failed. The problem was that "Allow 32-bit Applications" was set to TRUE in the application pool. DISABLING 32-bit apps (only allowing 64bit) resolved the problem on the new machine.
UPDATED FOLLOW-UP INFORMATION #2:
The ODAC installation on the new machine failed to place the installation and bin directory in the environment path (I hate Oracle). Once that was added, all was running as desired.
I have not worked with ODP.NET for quite some time, so I am running from memory of issues I had when I last used it.
The ODP.NET bits have to be installed on the server (or at least deployed, although I am not sure how that is accomplished off hand). The actual client in ODP.NET is the same Java libraries used for Oracle access. If installed, then you have some type of configuration error or permissions issue with using the underlying Java libraries.
I am not sure what the IDE message is about, however.
Hi i have an application developed on XP with Text ODBC drivers. But when i deployed on Win 7 with office 2007, i have connection issues.
<add key="SQLConnection.TextConnectionString" value="Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=c:\Data\;Extensions=asc,csv,tab,txt;Persist Security Info=False" />
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
i have googled every solutions like installing the following
http://blogs.msdn.com/b/sqlblog/archive/2009/12/29/how-to-connect-to-file-based-data-sources-microsoft-access-microsoft-excel-and-text-files-from-a-64-bit-application.aspx
Microsoft Access Database Engine 2010 Redistributable (32-bit)
2007 Office System Driver: Data Connectivity Components
after all of those, in my datasources(ODBC), it still only shows "SQL native client/SQL server/SQL server native client"
in the C:\Windows\SysWOW64\odbcad32.exe
i can see all the x32 drivers, but how can i modify my connection strings to access 32-bit Microsoft Text Drivers or are there any alternative solutions?
Thanks
I'm pretty sure it'll work automatically (even on a 64-bit machine) as long as the executing process is 32-bit.
Try recompiling to target x86 specifically.
You need the 64-bit Microsoft Access Database Engine 2010 Redistributable
http://www.microsoft.com/downloads/details.aspx?familyid=C06B8369-60DD-4B64-A44B-84B371EDE16D&displaylang=en
Then try
Microsoft Access Text Driver (*.txt, *.csv)
for the driver name.
AFAIK, all 64-bit ODBC drivers from the Microsoft Access Database Engine 2010 64-bit Redistributable have slightly changed their driver names, I guess to differentiate them from their 32-bit counterparts.
I had this exact problem and the recompiling to target x86 specifically worked! Note that in order to do this I had to specify the Target CPU in the advanced compiler setting dialog - Project Menu> Properties> Compile tab> Advanced Compile Options button.
Before finding this forum entry I did install the Microsoft Access Database Engine 2010 Redistributable (32-bit) but I don't know if that had any affect on this issue.
As mentioned above, when the executing process is 32-bit (in this case compiling against x86 makes the app 32-bit specific) the application will use the drivers from C:\Windows\SysWOW64\odbcad32.exe.
Thanks Cameron.
We were doing this from ASP.Net and got it working on Windows 2012 just by moving the one site into a separate app pool that had "32-bit Enabled" turned on in the advanced settings for the App Pool.
A lot of people seem desperate here, I want to offer a few solutions. But, first I want to highlight what a dated proprietary trash idea from the 90s this is.
Use Unix ODBC to host the text file from Linux which the docs (seem to) claim to support an implementation of the Microsoft text driver
A better option would be of course to import the CSV into PostgreSQL.
I would suggest just doing this with \COPY and dropping the notion of a CSV.
You can maintain the CSV with PostgreSQL acting as a server with the Foreign Data Wrapper (file_fdw).
If you don't want to run an RDBMS, the modern way would be to use SQLite. This is a great idea if you don't need the server/client model.
The ODBC->text interface is especially insane, because ODBC doesn't define configuration beyond connection (so I assume there are lots of assumptions there).
