And how you can change the name with dont research the file?
Research it for zero hours as previously stated.
How about giving the option to do a 0 hour research to allow you to change the name of the software. That way you can buy software and change the name of it. Include the cost of a normal 1 hour research so it sucks out some of the HPD from the game.
If you reply saying anything such as "You can do that by researching" I will reply with a "You = /FAILURE AT LIFE" message.
