installation problems

[patricia.aparecida]

I installed the 0.8.2-beta version of gephi in windows Vista operating system, with jdk1.8.0_05 and jre8; but when I do a double click on the icon gephi it will not boot. How can I solve the problem?

Dear patricia.aparecida

You need Java Development Kit (JDK) 1.7 to run Gephi, I had version 1.8 but it did not work, I installed 1.7 and I have Gephi running perfectly on windows 8 (x64) with Java 1.7 (x64).
The good news is that you do not need to uninstall Java 1.8, you can install Java 1.7 at the same time.

Instructions:
1. Head over to http://www.oracle.com/technetwork/java/ ... 80260.html and install Java 1.7
2. Go to your Gephi installation folder (probably C:\Program Files (x86)\Gephi-0.8.2) and locate the folder etc
3. Inside etc folder you will find a file named gephi.config, open this file with notepad.
4. Search for the keyword #jdkhome="/path/to/jdk"
5. Once you find this part of code, remove the # from the beginning since the machine will not execute this code and it will consider it as comment.
6. Replace the text inside double quotations /path/to/jdk with the directory address of your Java folder. In order to find your Java folder, check your windows drive (probably C:), and go to Program Files, and find the folder Java, inside that folder you will find a folder that starts with "jdk1.7". You need to copy the address of this folder and paste it instead of /path/to/jdk in the gephi.config file.
For me it was C:\Program Files\Java\jdk1.7.0_67.
7. Save the config file, if you are not allowed to do so save it on some other place and once done, replace it on the original file.

So to sum up, remove the # from gephi.config, replace the JDK path with your Java1.7 folder, and you're done!

Let me know if you have any questions, and please let me know if I can make these instructions any better in any way since I'd wish for it to be the ultimate solution for everyone, I had to run around in the forum to figure what I have to do.

Thank you for the instructions

I did exactly as you said and the gephi worked properly.

masoud, thank you so much, worked for me as well. Windows 8.1, 64 bit.

Thanks for the instructions. I was able to do this despite not having ever seen a .conf file before, so I appreciate the step-by-step clarity.

This Java site has so many items ... is it the java developer's kit? Can someone tell me the exact name of the Java kit to download?

... and reassure me it will work on Windows 7 64-bit.

thanks!

I am still having a problem
the config file reads ...

# ${HOME} will be replaced by user home directory according to platform
default_userdir="${HOME}/.${APPNAME}/0.8.2/dev"
default_mac_userdir="${HOME}/Library/Application Support/${APPNAME}/0.8.2/dev"

# options used by the launcher by default, can be overridden by explicit
# command line switches
default_options="--branding gephi -J-Xms64m -J-Xmx512m -J-Xverify:none -J-Dsun.java2d.noddraw=true -J-Dsun.awt.noerasebackground=true -J-Dnetbeans.indexing.noFileRefresh=true -J-Dplugin.manager.check.interval=EVERY_DAY"
# for development purposes you may wish to append: -J-Dnetbeans.logger.console=true -J-ea

# default location of JDK/JRE, can be overridden by using --jdkhome <dir> switch jdkhome="C:\Program Files (x86)\Java\jre1.8.0_25"

# clusters' paths separated by path.separator (semicolon on Windows, colon on Unices)
#extra_clusters=

However this still does not work - the location of my java file is .. C:\Program Files (x86)\Java\jre1.8.0_25
