If the software is not compatible with your version of Symbian OS, then you have to find a newer or older version of the software that is supported by your OS to be able to install.
If there is no other version available, then I am sorry, that program will not work.
The different versions of Symbian OS are binary incompatible or incompatible on hardware input.
I think if it is hardware incompatible, you can force it to install, but don't becasue you can start it but there is no way to make a touch screen to work as a keyboard to control the program (at least I could do that on the program I want). Therefore the program is useless.
