Gephi is a free software which costs users nothing. On the other hand, we may not expect the same level of stability as provided by the commercial software. One of the common problem is the comparability of Gephi with the Java platform installed.

Gephi 0.9.0, Gephi 0.9.1, and Gephi 0.9.2 have been tested on Java 7 and Java 8. Therefore, you are recommended to have these versions of Java installed on your computer.  Check the following website for these versions of Java platforms:

If you have Java installed, but the Gephi reports that it cannot find the Java platform. One possible reason is that the Gephi installation failed to locate the path of your installed Java platform. You can correct this problem by following these steps:

(1) Open configuration file under the installed folder of your Gephi, for example, C:\Program Files (x86)\Gephi-0.8.2\etc\gephi.conf, depending where you install your Gephi.

(2) Specify jdkhome=”C:\Program Files\Java\jre8″, the specific path you put here depends on where you install your Java platform. Please de-comment out this line by removing the “#” symbol after you change the default specification.
