Dear All, I do not usually post on this Forum, but everyone's messages have helped me through low patches, especially late at night! I am posting this message to ask whether anyone is using ArcGIS on a Windows 7 64-bit operating system? My University currently uses ArcGIS version 9.2, but this seems to be incompatable with Windows 7. I have had a look on ESRI's website and they claim that ArcGIS version 9.3 is compatable with Windows 7, but independant forums suggest otherwise. I only have the home edition of Windows 7, so I cannot run the programme in XP mode. Silly Windows!!!! Any advice would be gratefully received :-)
