I bought a laptop with core i3 processor which is 64 bit. In this i cant install some software such as turbo c, JAVA, microsoft visual studio and so on. How to get recover this problem?
Find compatible software for 64 bit or install the 32bit version of Win 7. The processor has 0 bearing on what software you can run, it's the operating system you need to worry about. You probably need to update the software versions you have.
