Hi All,

1. What is the difference between 32Bit & 64Bit applications.
2. Can we run a 64bit application on a 32bit OS (I think NO). I have XP prof SP3 I originally installed it in year 2006.


Thanks

32 bit app uses 32 bit cpu registers and instructions and addresses.
64 bit app uses 64 bit cpu registers and instructions and addresses.

2. No.
