این ایمیلی هست که خود شرکتش بهم جواب داد، ضمن اینکه همه ی کارایی که گفت انجام دادم ولی بازم به نتیجه نرسیدم، یه نگاهی شما به لینکی که داده بکنید، شاید چیزی فهمدید :
Hello hamed,
First, thank you for your interest in our suites.
As for your question. First please make sure the .Net Framework 2.0
installed on the machine which have the problem. I should also say the
CopyLocal property for our assemblies should be set to False. I also
suggest that you review the "How to distribute applications which use
Developer Express .NET Windows Forms controls" article which can be found
at: www.devexpress.com/kbA240. This article should help you resolve the
problem.
