0.6 amd64 release for Windows crashes on JOGL load

[Patrick Lucas]

When I select Workspaces->Add the application crashes with the message "java.lang.UnsatisfiedLinkError: E:\dev\tools\gephi\gephi64\lib\jogl\jogl.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform".

My environment: Windows Vista 64-bit on an Intel Core 2 Duo E8400.

Stack Trace:

[Mathieu Bastian (mathieu.bastian)]

Do you use a 64bit JVM ?

[Patrick Lucas (prl)]

The .exe was using the wrong JVM for some reason. The proper JRE was set as default in my PATH, registry, and C:\Windows\System32 dir but it was using an old 32-bit one.

After removing the old JRE it now works, but perhaps Gephi should check whether JVM is 32- or 64-bit on startup?

Or perhaps it could take a JVM as an argument?

Thanks for the help.

[Mathieu Bastian (mathieu.bastian)]

0.7 release work with 64-bit JVM. Additionnaly you can select which JRE or JDK to use in the configuration file.
