Thanks for your coments,
I am running my compiled program on Windows XP. it is true that one is home and the other is proffesional, but i think that this is not the problem.
I just create a form with a couple of speedbuttons for to close the form. That is. I didn´t use special tools in this form. I compilet itand run without problems in the computer with lazarus, and not in other compiter with equal and similar operative system.
Error message is something as "windows dont have access to this hardware, path or file. Are you the administrator of this computer?
I didn´t use any spacial path, API, or whatever, but it only run under next path on other computers different for the design pc: "C:/"
How can i do for to run my program in other paths?
Thanks!!
