So my computer was recently rebuilt and all my settings were re-imaged to a new computer. This meant that most drivers were not re-installed. Right now I have a bunch of USER DSN that are invalid. I cannot remove or configure them. I get the following error when I try either: http://imgur.com/a/drBkI
Google tells me to go to regedit but nothing exists in the following folder HKEY_LOCAL_MACHINE\Software\ODBC\ODBC.INI\ODBC Data Sources.
I tried just re-installing the the Posgres ODBC driver but no go. Ran data sources administrator GUI as an administrator and windows still won't let me remove them.
Not all data sources are in that key, especially if you have a 64 bit machine. 64-bit ODBC explains where you can find 32/64 bit data sources in the registry.
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBC.INI
HKEY_CURRENT_USER\SOFTWARE\ODBC\ODBC.INI
It also explains about registry redirection. The key you are looking is for system DSNs even on a 32 bit machine so you want to look in HKEY_CURRENT_USER.
