Didn't want to ask but I've tried for a couple of hours now....
 

You guys helped me get unicenta running by going into terminal and cd /home/jason/unicentaopos-3.91.2 then sh start.sh.

I can go into terminal every time and get the program running this way. I'd like to create a desktop shortcut so I can just click and the program starts. I'm using Mint 17 Cinnamon.

I've right clicked desktop and clicked create new launcher but nothing I put in will allow me to click the OK button so I must be doing something wrong.

Thanks in advance.

Is start.sh set as executable? If it is then just put the following in your shortcut:
jdk

I've tried that and several other possibilities. No matter what I put in the OK button does not activate so I cannot click it.
Thanks

Show us the properties of start.sh

example on mine

That is what members need to see plus your launch string command you put on your icon.

L.E. Ignore this.. I've reread your second comment and I was wrong.. Just try running this once:
Then everything should work as you desire...

Great! That opened up the OK box, and now is clickable. However, I dont know if I should check launch in terminal or not?

Both options should work...

I love learning new things and I always eventually become very good at what I work at but this is very frustrating. Now I've tried it with launch in terminal checked and unchecked, and I have a desktop icon, however nothing happens when I click on it. ????

Try to edit that desktop link and set the working directory to /home/jason/unicentaopos-3.91.2 and the command to start.sh

Found this about installing Unicenta in Ubuntu. This may apply to Mint as well?

3. Fix uniCenta oPOS launcher.

uniCenta oPOS creates a fautly desktop launcher icon in Ubuntu.
To fix this we need to first move and fix the launcher, open a terminal and enter:

cd ~/Desktop
sudo sed 's/Exec/#Exec/g' "uniCenta oPOS.desktop" > /tmp/.unicenta.desktop
sudo echo -e "\nExec=sh /opt/unicentaopos-3.01/start.sh" >> /tmp/.unicenta.desktop
sudo rm "uniCenta oPOS.desktop"
sudo mv /tmp/.unicenta.desktop "/usr/share/applications/uniCenta oPOS.desktop"

4. Fix start.sh

As strange as it may seem, the start.sh file has control characters (^M) in that prevents the program from running correctly on Linux.
To fix this we create a new start.sh file in the installation directory with the non printable characters removed.

sudo cat /opt/unicentaopos-3.01/start.sh | sed 's/\o015//g' > /tmp/.start.sh
sudo mv /opt/unicentaopos-3.01/start.sh /opt/unicentaopos-3.01/start-original.sh
sudo mv /tmp/.start.sh /opt/unicentaopos-3.01/start.sh

All that is left to do is to make the start.sh file executable:

sudo chmod +x /opt/unicentaopos-3.01/start.sh

You will now be able to find uniCenta in the Dash and start the application.

This was why I asked you if start.sh was executable.
