System specs: 64-bit OS (Win7), 64-bit R (3.3.3), 32-bit MS Access (2016).
I have data in a 32-bit .accdb file and I want to read it into R. I tried this:
con <- odbc::dbConnect(odbc::odbc(),
dsn="MS Access Database")
but saw the following error:
Error: nanodbc/nanodbc.cpp:950: IM014: [Microsoft][ODBC Driver Manager]
The specified DSN contains an architecture mismatch between the Driver and Application
Web search indicated that the bit difference between R and the database is the culprit. The default ODBC manager in Windows doesn't include drivers for MS Access (or rather, it seems to, but attempting to manage them using that tool gives you an architecture error). Following other advice, I used the ODBC manager for 32-bit programs (c:\windows\sysWOW64\odbcad32.exe) to create a new DSN with a new name for MS Access files, and then called this DSN:
con <- odbc::dbConnect(odbc::odbc(),
dsn="MSAccess32")
I got the same error, however, and suspect there is something I don't understand about what this error means. Is there a known workaround for the problem?
The access file itself knows nothing about bitness, its only about the client application and the bitness of the odbc driver:
If your R is 64 bit, you need the 64bit ODBC driver for access and therefore also use the odbc manager for 64bit, which is C:\Windows\System32\odbcad32.exe (in Win7 64bit).
While if your R is 32bit, you need the 32bit ODBC driver, located at C:\Windows\SysWOW64\odbcad32.exe.
You can download the required Access Database Engine 2010 Redistributable from here: https://www.microsoft.com/en-US/download/details.aspx?id=13255
So, download the 64 bit Access Database driver, create a 64bit DSN entry and you should be fine.

Getting this error message when attempting to connect to a FoxPro database via a DSN on a Windows 7 x64 PC:
The specified DSN contains an architecture mismatch between the Driver and Application
This project uses Visual Studio 2005. The connection settings point to a 32-bit DSN ODBC configuration correctly. Not using the default x64 ODBC DSN. I even went into the registry (Wow6432Node) to make sure the FoxPro driver was pointing to the driver in the 32-bit location (sysWow64 directory).
Stumped - any ideas?
The Visual Studio 2005 project was configured for "Any CPU", and needed to be set to x86 explicitly. That was the difference, even though the DSN was pointing to the correct 32-bit driver.
Platform target: x86
I have some old VB6 code that requires an ODBC data source and I'm trying to run it on Windows 7 64-bit but I get this error:
System.ApplicationException: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application
Why?
Quick answer:
To manage a data source that connects to a 32-bit driver under 64-bit platform, use c:\windows\sysWOW64\odbcad32.exe.
To manage a data source that connects to a 64-bit driver, use c:\windows\system32\odbcad32.exe.

I have created an ODBC connection in PB10 Data Source and once I attempt to connect, below stop sign error occurs. Any idea on how to resolve this kind of connection error?

Also, you could try to create the 32-bit ODBC in the 64-bit Operating System.
Here's the exe you need to execute to create 32-bit ODBC in a 64-bit Operating System.
c:\windows\syswow64\odbcad32.exe
Use odbcad32.exe under C:\Windows\SysWOW64\ to configure the DSN.
I suspect that you are on 64-bit system and that the DSN you try to connect to uses a 64-bit odbc driver. PowerBuilder applications are 32-bit and can only use 32-bit odbc drivers.
We have an ASP.net web-app running in the following environment -
Existing Environment
Operating System : Windows 2003
Framework : .NET Framework : 2.0
IIS : 6.0
Database : Oracle 10g
We wished to upgrade this to the following environment
Present Environment
Operating System : Windows 2008 R2 x64
Framework : .NET Framework : 2.0
IIS : 7.0
Database : Oracle 11g
While doing so, we face the below issue
ODBC Connection Issue on Windows Server 2008 R2 64 bit
ODBC connection could not be established from the ASP.net Web Application in Windows Server 2008 R2.
Application throws an Error : ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.
Connection String :
<add name="ConnectionString" connectionString="Driver=Oracle in XE;Dsn=winerenew;uid=winere;pwd=winere;dbq=XE;dba=W;apa=T;exc=F;fen=T;qto=T;frc=10;fdl=10;lob=T;rst=T;btd=F;bam=IfAllSuccessful;num=NLS;dpm=F;mts=T;mdi=F;csr=F;fwc=F;fbs=64000;tlo=O" providerName="System.Data.Odbc"/>
Application works perfectly in windows 2008 x86.
We have tried the following ways to resolve this issue in Windows Server 2008 x64,
1) Enabled the 32-Bit Application in the Application Pool (IIS 7)
2) Executed the ODBC 32 Bit driver with the following command C:\Windows\SysWOW64\odbcad32.exe
3) Installed the oracle 64-bit ODBC driver.
The above methods doesn't seem to solve this issue. Could anyone tell me the problem behind it and the solution to solve this issue?
Set default ODBC driver.
From the Windows Start menu, click Control Panel > Administrative Tools > Data Source (ODBC).
Open the System DSN tab.
Select ODBC_NAME and click Configure.
Normally system use 32 bit ODBC as default. but if you dont have 32bit then configure 64bit and set as default.
For me it's working.
I build VS application in 64bit and published on IIS by setting default ODBC driver. O
If you have working DNS then you can enable tracing ODBC calls from odbcad32.exe. Then test Oracle connection from any ODBC editor/tool (I often test it with simple Python program that uses odbc module). Such tracing will create file with a successful attempt to connect to database. After connecting do database close program, stop tracing and rename trace file.
Now you will have to create such tracing for your application: enable tracing, start your program, try to connect do database, close program, stop tracing. You have two files with attempts to connect to database via ODBC: one successful and one with failure. Compare them.
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

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).
