Can't start the linux community installer on Centos 5.5 64-b

[twhitehead]

When I try to execute the installer, nothing happens.
I have found other people who had the same problem on other versions of 64-bit linux and their solution was to install ia32-libs.
eg:

However Centos (and Redhat / Fedora) apparently do not have ia32-libs or an equivalent.
Does anyone know what libs I need to install in order to get the installer to run?

Which version are you installing?   The current version which is 4.0 does not have a 32 bit installer.

I am trying to install this version:

alfresco-community-4.0.b-installer-linux-x64.bin

I have tried

./alfresco-community-4.0.b-installer-linux-x64.bin –mode text‍

I have made sure the file is executable.
I have installed vnc and tried double clicking the file.

There is no response to any of the above. It doesn't give an error at all, it just returns to the prompt immediately.

Having failed to find a solution to my problem above, I have tried:
Doing a manual install on JBoss 4.2.2 without success.
Doing a manual install on tomcat 6.0 without success:
I get the errors

java.io.FileNotFoundException: alfresco.log (Permission denied)‍

and

org.alfresco.error.AlfrescoRuntimeException: 10100001 Keystores are invalid‍

which I have not yet found the solution to.

I have tried the easy install for the previous version: 4.0.a and it gives me the same problem as 4.0.b ie running the executable does nothing at all.

I have tried version:3.4.e and I get the error:

bash: ./alfresco-community-3.4.e-installer-linux-x64.bin: /lib64/ld-linux-x86-64.so.2: bad ELF interpreter: No such file or directory

If anyone can suggest what the best way to proceed is I would appreciate it.
