Everytime I try to use ArcGIS Desktop the program closes. It happens when I try to add a basemap or try to use a tool.
This message appears when the program closes: "ArcGIS Desktop has encountered a serious application error". I installed the Microsoft .net Service Pack 1, I uninstalled the program and reinstalled it again and it keeps closing. I am not able to work with it. What can I do to fix it?
