When downloading Google Earth, whats the difference if I select Run or Save from File Download Security Warnin

When downloading Google Earth, whats the difference if I select Run or Save from the File Download Security Warning Dialog Box? They both seem to place the Google Earth in my Settings and Documents. If I turn off/on the computer I can still access Google Earth whether I choose to Run it or Save it during download. If I select Run the download procedure is more automatic and quicker with less things I have to do. If I chose to Save, then I can choose where I can save it to, but it still places a part of Google Earth in Settings and Documents I am hoping there are other differences. Thank You.

i think there is no more differences if u save file it will b save as a back up also if u run that files will b saved temparary and after installation those files will b deleted
Reply:When you click Save it saves the installation files to the destination folder, not the application, whereas if you just click Run it will run the installation file but it will be a temporary file that will be deleted once you clean your cookies and stuff out. To change where Google Earth is located you have to change the directory in the installation process
Reply:Either of the ways u select, the setup files will definitely be downloaded to your local machine first. Its only that opting "Run", will save the files in temporary folder(as in ur case, documents %26amp; settings) and start installation automatically but will get deleted gradually once the maximum limit of the folder is exceeded. So it will reside in the folder until its in limit size. Whereas if u choose to 'Save', it will ask u to select a folder u want to save the files in. This will not get deleted automatically and u can keep it for installations in future!
