Software needs fixing.

I have softwar previously written which is having problems with XP systems. Sometimes it works sometimes it doesn't. There is no rhyme nor reason as the error message does not say anything except it caused an error. I need this corrected to work on XP. It is written in Delphi. It is a simple graphics program. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform All Windows platforms.
