Greetings fellow GIS-ers!
I am drag and dropping some CAD files of various extensions into a new map document and receiving the following: 'Could not open the specified file'. I have received this message attempting to add every CAD file I tried, adding by 'drag and drop' or by the add data button. Some background - to resolve an earlier issue, it was suggested by ESRI tech support that I rename the ESRI directory in Documents and Settings\All Users\Application Data\ to ESRI_OLD and in the registry (using regedit). Did this reset a CAD related setting as it did the rest of my settings or is something else afoot? I was able to display all CAD files before this change was made.
Thanks for your input!
