I recently had an issue where after the installation of a Third party Client side tools, we were not able view the drivers listed in the ODBC Data Source Administrator (odbcad32.exe).

In order to create a DSN to use this third party driver, we had to take a backup/export of the registry key of an existing DSN, edit the content of the registry and rename the existing DSN name to new DSN and then had to merge it back to the registry.

We did check that we had the sufficient privileges on the system, the third party client tools is properly installed and we are able to use this driver for connecting to the third party databases without any issues. So we realized that the issue is not with the third party driver rather it is the registry key from where the ODBC Data Source Administrator (ODBCAD32.exe) actually picks up the list of drivers.

The ODBC Data Source Administrator (ODBCAD32.exe) picks up the list of entries from the following registry path.

On a x64 bit system for a x64 bit drivers: HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INIODBC Drivers

On a x64 bit system for a x32 bit drivers: HKEY_LOCAL_MACHINESOFTWAREWow6432NodeODBCODBCINST.INIODBC Drivers

On a x32 bit system:

HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INIODBC Drivers

Note: Above screenshot is taken from a x64 bit system for a x64 bit driver

We realized that the values for the following registry keys should always be (value not set) and if the value is set to an empty string or any other value (either by Third party application or open this registry and close it without any changes) we will run into similar kind of issues where the drivers are not listed in ODBC Data Source Administrator (odbcad32)

On a x64 bit system for a x64 bit drivers:

1) HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INIODBC Drivers(Default) and

2) HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INI(Default)

On a x64 bit system for a x32 bit drivers:

1) HKEY_LOCAL_MACHINESOFTWAREWow6432NodeODBCODBCINST.INIODBC Drivers(Default) and

2) HKEY_LOCAL_MACHINESOFTWAREWow6432NodeODBCODBCINST.INI(Default)

On a x32 bit system:

1) HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INIODBC Drivers(Default) and

2) HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INI(Default)

So in order to make this change we would need to perform the following registry changes.

1. Please note before modifying any registry entries we would recommend you to perform a backup of the registry. Please refer the following article on how to backup and restore the registry.

How to back up and restore the registry in Windows: http://support.microsoft.com/default.aspx?scid=kb;EN-US;322756

  1. Login using an administrator account and bring up the registry editor.

a. On Windows Vista and later - Go to Start Run and enter the following: regedit

Click OK and the Registry Editor will open.

b. On prior versions of Windows

Start > Run > type Regedit.exe and press Enter or

Oracle 11g Client Odbc Driver 32 Bit Download

Start > Run > type Regedt32.exe and press Enter

  1. HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INIODBC Drivers and HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INI
  2. Right-click the key called ' (Default) ' and select Delete option.
  3. If unable to delete the key, double-click the key and erase the Data value entered. Once done, the value should read ' (value not set) '.
  4. Close the Registry Editor and re-launch the ODBC Data Source Administrator (ODBCAD32.exe).

On a x64 bit system for a x64 bit driver:

a. Go to Start Run and enter the following: odbcad32.exe (By default this will load the odbcad32.exe from C:WindowsSystem32odbcad32.exe).

Click OK and the Registry Editor will open.

On a x64 bit system for a x32 bit driver:

a. Go to the following path C:WindowsSysWOW64 and open the odbcad32.exe

(This will load the 32 bit version of ODBC Data Source Administrator)

On a x32 bit system:

a. Go to Start Run and enter the following: odbcad32.exe (By default this will load the odbcad32.exe from C:WindowsSystem32odbcad32.exe).

Click OK and the Registry Editor will open.

We should be able to successfully see the drivers listed in the drivers Tab and should be able to create the DSN’s using that driver.

Or

1. To make this even easier we just need to execute the following command in elevated command prompt and refresh the registry

reg.exe DELETE 'HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INIODBC Drivers' /ve /f

and

reg.exe DELETE 'HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INI' /ve /f
