Open Source Document Management System | OpenKM

I have read many many installation guides but they either are missing points or assume certain things are already running.

iv installed java, iv installed tomcat 7 and confirmed it works (don't even get me started on that with the users).

ok so I'm in a fresh 32 bit Ubuntu. I download the correct installer.
I do the chmod command
I then run it.
it installs, it picks the opt directory (exactly as shown in documentation)
then it finishes
no short cut on desktop and none of the start / stop files can run.

why would this be the case.
an another test version using 14.04 64 bit I had to change folder permission after installation to get any of it to run. (none of this mentioned in installation notes)

problem with this one is I have to click the start openkm after every reboot.
tried following the setup as a start up service but every time I do the start service command it says failed (this was a tomcat service)
now I don't know if this is documentation confusing between having tomcat run or openkm start up, I don't know because its not exactly clear.

if some one would be so kind as to help me out I would be forever appreciative.
am I better off switching to 64bit 16.04 to start with.

I suggest forward to 64 bits architecture. Default setenv.sh environment comes with 2GB of ram configuration ( by default ). Java have problems on 32 bit architecture when trying to use 2GB of RAM, I suspect this is your problem. You should reduce it, or change to 64 bits. Our suggestion, for starting, is a 64 bits with 4GB of RAM and 2 Core.

Try starting application from terminal. Go to $TOMCAT_HOME/ bin folder and execute the command "./catalina.sh run" you'll see there the error, probably what I've commented.

ok thanks for reply.
i will use a fresh install and go from there.
i am still unhappy with the fact in the last install no desktop icon was created and permissions seemed to be out of whack.
i had to set as executable but no mention of this in setup.....??!!!?!?!?!
