I have been using Geogebra for windows in my windows 7 laptops for years. Usually administrator's privilege is not necessary in order to start a geogebra.
However, recently, I found Geogebra would not start unless I run it as administrator; this weird issue occurs first in one of my laptop, then spreads like a virus to another. Currently, the third computer does not have such a issue.
So this does not seem like a problem with Geogebra itself. The common phenomenon I met in the two problematic laptops is: Adobe Acrobat does not work and has been reinstalled, which probably has something to do with the current issue but I am not very sure.
Currently, if I double click geogebra without admin's privilege, the geogebra.exe and javaw.exe processes appear in sequence in task manager windows for 1 or 2 seconds and then disappear. Only when running as admin, the javaw.exe can be normally started.
I tried to uninstall geogebra and clear the registry information, update the java to the latest version, reinstall geogebra with the latest version, ... all these efforts do not solve this issue.
Are there any hints for me to try in order to solve it?
Very nice answer and approach! – redbeam_ – 2015-09-29T12:17:24.877
