GeoGebra Installation

My computer crashed, where's my work?

Have a look in the computer's temporary folder and look for the most recent file like GeoGebraUndoInfo6533063557894725659.ggb

Quickest way in Windows: http://www.tomshardware.co.uk/faq/id-2082907/temp-folder-windows.html

Press Windows R and type

%temp%

then Enter.

What's happened to offline export as a webpage?

If you upload your worksheet to https://www.geogebra.org/materials then you can download it as an "Offline Worksheet (.zip)"

Where is the online version?

https://www.geogebra.org/graphing

Error "A Java Exception has occurred"

Delete this folder: C:\Users\<username>\AppData\Roaming\GeoGebra 5.0

This is a hidden folder, so can be hard to find. One way is to press <Windows>R and then copy and paste this (changing <username> to your Windows username)

explorer /n, /e, /select, C:\Users\<username>\AppData\Roaming\GeoGebra 5.0

then right-click -> Delete

GeoGebra Won't Start

Delete this folder: C:\Users\<username>\AppData\Roaming\GeoGebra 5.0

(see previous question for more details)

I updated GeoGebra, but it keeps reverting to the previous version

Delete this folder: C:\Users\<username>\AppData\Roaming\GeoGebra 5.0

(see previous questions for more details)

Support for OSX 10.6, 10.7

Please try the version with Java 7 or upgrade for free to OSX 10.10

CAS View doesn't work in the Portable version (Windows)

Right-click on GeoGebra.exe and Run as Administrator

How do I get the OSX version without going through the Mac App Store?
