This is really something for the World Community Grid forums, but alas. WCG doesn't have a 64bit science application for any of its sub-projects, as that's what it's asking for. They only have 32bit applications and not necessarily for all sub-projects either. But you best ask that at their own forums, or wait for Sekerob to pass by here (We never know when to expect him ;-)).

In the mean time, start by installing the 32bit compatibility libraries for your Linux version. See here for more info on that.

If you are running 64 bit Linux and 64 bit BOINC then you might have a problem with projects that issue 32 bit applications rather than 64 bit applications. To allow 32 bit applications to run on 64 bit Linux you must install 32 bit versions of certain shared libraries. The names of the packages containing the 32 bit libraries is different for each distro.

Thanks for your help !

Thats it.........

Using terminal and command : uname -a
I found I was using Ubuntu 11.04 64 bit OS !

IE :
Linux ubuntu 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011 x86_64 GNU/Linux

The x86_64 is 64 bit OS !

If it said i686 it would be 32 bit OS.

I installed the Four packages that are required for 64 bit compatability
and it worked fine for me.


Thanks again !
