I wanted to transfer 32-bit ODBC System DSN on XP machine to 32-bit ODBC System DSN on Windows 7 64-bit machine. So, I went to Regedit and exported ODBC.INI folder (HKEY_LOCAL_MACHINE &gt;&nbsp;Software &gt;&nbsp;ODBC &gt;&nbsp;ODBC.INI). From Windows 7, I ran *.reg file and imported. It went successfully, but it was imported into 64-bit ODBC System DSN and I can't delete them. When I tried to Remove, it says &quot;The setup routines for the Microsoft Excel Driver (*.xls) ODBC driver could not be found. Please install the driver.&quot; I just want to delete them. How can I do that? Thank you very much in advance. HB
