second question first, yes it's possible to install Delphi 2010 in 64 bit Windowsoperating system.
first question is to vague to be answered ...
------------------------------------------------
thank you very much for your reply, is that the same process to install Delphi 2010 in 32 bit and 64 bit ?
i am trying to explain my first question again : i have made an interface with some menu button , for if i click on menu buttonA then one WindowsB will show on the screen , if i run it on windows XP then it works but if i run the program in Windows 8 then it does not ,for example when i click on buttonA then it does show the windowB, can you suggest me the possible reason for that please ?
