right now i'm using arcgis 10.2.2 on a free trial version,suppose my two months trial version is done can i update it again or i cannot use it anymore after my two months is over..Thank You
I believe that you will only be able to get the free trial only once per version. ArcGIS for Desktop 10.3 will be released fairly soon and you may be able to get a free trial of that.
Then That means if my trial version is over i cannot use ArcGIS anymore???..that is sad... then what shall i do if i cannot use it anymore....
You could look into purchasing a home use license:
ArcGIS for Home Use Program | ArcGIS for Desktop Advanced for Personal Use
