An underlying database error occurred. Class not registered. </SPAN><BR /><BR /><SPAN>I saved the file under the .xls extension and it worked. I am running the dinosaur 9.3 version but have never had a problem with it handling files in windows 7 before. Why am I suddenly getting this error when trying to bring .xlsx files into the program?</SPAN><BR /><BR /><SPAN>Thanks, Kirian</SPAN></BODY></HTML> Thu, 03 Jul 2014 14:46:01 GMT https://community.esri.com/t5/data-management-questions/failed-to-connect-to-database/m-p/496692#M28214 KirianHeffentrager 2014-07-03T14:46:01Z Re: Failed to Connect to Database https://community.esri.com/t5/data-management-questions/failed-to-connect-to-database/m-p/496693#M28215 <HTML><HEAD></HEAD><BODY><P><SPAN>I had the same problem with 10.2.1 and excel arcgis 2013, resolved converting excel to dbf file. on this page you can do the conversion without downloading software any or drivers to find the office: </SPAN><A class="jive-link-external-small" href="http://www.elconvertidor.com" rel="nofollow" target="_blank">http://www.elconvertidor.com</A><SPAN>.
