Geogebra won't start unless running as administrator

:flushed:


Recently in one of my windows 7 laptop, I found geogebra could start without administrator's rights.

However, this seems not be an issue of geogebra itself; because in another win7 computer, it works OK even without administrator's previlidge;


The phenomenon I observed is:


When I click the geogebra link or try to open it, there appears the "javaw.exe" process for 1 or 2 seconds and then it disappears and Geogebra cannot start.


I have updated my Java into the latest 1.80_60; an abnormal issue in the C:\programdata\oracle\java\javapath directory is, all the three system link files: java.exe, javaw.exe and javaws.exe are directed to the wrong location (perhaps ealier java versions?). So I changed them into the current: d:\program files\java\jre1.80_60\bin, but this does not solve the problem. :flushed:

In this case I'd do the following:

- open Java control panel and delete any installed old GeoGebra webstart versions (because javaw runs... it makes me think that there are some sparse remnants)

- uninstall GeoGebra and cleanup the windows registry for related entries (by hand, by cccleaner, by norton, by whatever you want)

- reinstall GeoGebra, downloading a fresh version from this site. For some time now, ggb is equipped with its own java version, so there's no need to mess up with the installed java.

thank you for guidelines.


I can only verify the third one, geogebra does not need the installed java since even when I uninstall Java it still works well.


For the first one, from the Java control panel, I cannot find the webstart version geogebra though I remember I did install it before and eliminated it by just deleting;


The second one, I used YourUninstaller to uninstall and clean geogebra (including registry information), but it seems there is still something remained: because when I reinstall geogebra with the latest release, the former user defined setting saved is still active (when I open geogebra with administor's right, the layout is user defined version not the geogebra default).


so far, it remains a problem to me :(

This seems to be a problem caused by illegally modifying registry information.


Since there is no system image backup, I just deleted the current user account from Administrator, and then created a new user account, which solved the issue. :smiley_cat:
