The place where I work have recently installed a tool on our computer systems. However there are a few things that I don't quite like about the tool and would like to improve them. However I am wondering if this possible?

I'd like to point out a couple of important things:

  • The software came pre-installed. I didn't install it and never agreed to any EULA
  • I have made reasonable effort to find the EULA - by downloading the setup system and also checking the site, however I could not find the EULA anywhere.

Does this mean that I can reverse-engineer the application to fit my needs better? I don't plan on making any commercial benefit from this or re-distribute it as my own. However I do plan on passing the fixed code to the others at work if it will also serve of help to them.

Not without permission

The creator of the program has copyright in it: you are proposing to make a derivative work and for this you need permission.

    Thank you for that. It appears that the system has been abandoned and no longer actively maintained as of late. I have tried to contact the developers but have not received any feedback as of yet. Is there any clause (such as educational purposes) which would allow me to de-compile and fix the code as "fair use". In addition - though this might come across as cheeky - would adding a disclaimer stating that this was done for x purposes and should be immediately deleted, free me from the burden of liability? I'm just checking the options at this point rather than trying to infringe copyright.

    No and no. Someone, somewhere owns the copyright - it's quite likely they either don't know or don't care that they do but they can exercise their rights at any time
