Install Microsoft Excel Driver (*.xls *.xlsx *.xlsm *.xlsb)
I'm having a problem with the ODBC connection that is supposed to connect to an Excel table and do stuff with it. I've already read a lot stuff on the internet about it, but none of the solutions helped me (including stackoverflow).
Install Microsoft Excel Driver (*.xls *.xlsx *.xlsm *.xlsb)
'When I attempt to create a new System DSN for an Excel 2010 Spreadsheet from within Impromptu, the above drive for the 'Create New Data Source' is unavailable. If I go to Control Panel/Administrative Tools/ Data Sources and attempt to create a System DSN, I have the above driver available. Feb 27, 2013 - Hi OS: Windows 7 64bit; Office 2007; Used Excel file type: *.xls (must be compatible with Office2000 and with Office2007) I have an application.
So basically I am at a point where I'm trying to open a connection to a table.
When I call the excel.Open() method, I get OdbcException with message:
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified', which is odd because I have those specified in the string named con.
It's also worth to mention that in the ODBC Data Source Administrator, I can clearly see that I have those drivers installed and running.
There is also another odd part. When I call the following method I found on stackoverflow it returns me the following list of drivers:
- 'Driver da Microsoft para arquivos texto (*.txt; *.csv)'
- 'Driver do Microsoft Access (*.mdb)'
- 'Driver do Microsoft dBase (*.dbf)'
- 'Driver do Microsoft Excel(*.xls)'
- 'Driver do Microsoft Paradox (*.db )'
- 'Microsoft Access Driver (*.mdb)'
- 'Microsoft Access-Treiber (*.mdb)'
- 'Microsoft dBase Driver (*.dbf)'
- 'Microsoft dBase-Treiber (*.dbf)'
- 'Microsoft Excel Driver (*.xls)'
- 'Microsoft Excel-Treiber (*.xls)'
- 'Microsoft ODBC for Oracle'
- 'Microsoft Paradox Driver (*.db )'
- 'Microsoft Paradox-Treiber (*.db )'
- 'Microsoft Text Driver (.txt;.csv)'
- 'Microsoft Text-Treiber (*.txt; *.csv)'
- 'SQL Server'
- 'SQL Server Native Client 11.0'
None of those have the '*.xlsx' in them, which is the format of a file I'm trying to read.
The method is the following:
It should be noted that when I actually go to the regedit and find those values I clearly see:
Am I missing something obvious? Please help me :)
By the way I'm pretty new to this side of .NET so please keep your answers dumbed-down so I could actually understand what is going on. Thank you!
EDIT:A friend pointed out I should give more information, so here is the screenshot of the regedit, ODBC Data Source Administrator and the proof that the ACEODBC.DLL actually exists on my hard drive:
Also the con.ToString() gives the following:

How about using OleDbConnection, and you have to install Microsoft Access Database Engine 2010 at first.
I Looks like your application is a x86 (32bit) application and you are looking at the 64 bit ODBC driver. Check if the 32bit ODBC driver is installed..
Make sure you have downloaded and installed the Microsoft Access Database Engine 2010 Redistributable..

If you are trying to query a MS Excel (.xls, .xlsx, .xlsb) or MS Access (.mdb, .accdb) file on a 64-bit server and are getting one of the following error messages:
- The ‘Microsoft.Jet.OLEDB.4.0’ provider is not registered on the local machine.
- The ‘Microsoft.ACE.OLEDB.12.0’ provider is not registered on the local machine.
Then it is necessary to install 2010 Office System Driver Beta: Data Connectivity Components on the server (the reason for this is the old Jet4.0 drover does not exist for 64 bit, and the ACE driver needed to read the newer formats is not installed by default). If you are using a version of Windows with UAC enabled, be sure to do this as Administrator.

After installing the components, use the following connection string formats (from the page linked-to above):
- Using OLEDB, set the Provider argument of the ConnectionString property to “Microsoft.ACE.OLEDB.14.0”. Example: “Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Path_To_File”
- Using OLEDB and connecting to a Microsoft Office Excel file, add “Excel 14.0” to the Extended Properties of the OLEDB connection string defined in the previous bullet point.
- Using ODBC:
- Connecting to Microsoft Office Access (.mdb or .accdb): set the Connection String to “Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=path to mdb/accdb file”
- Connecting to Microsoft Office Excel (.xls, .xlsx, .xlsb): set the Connection String to “Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DBQ=path to xls/xlsx/xlsm/xlsb file”
