Interesting Correspondence with the Manager (Pierre Vandevenne) of www.datarescue.com

You would have to work for a company that makes software or tests software for another company. Like stated in the post before, usually its used in security to check for holes in a app or system. I actually use IDA to dissasemble games. That way I can modify them to my liking.

For the hobbyists (like crackers) it might be expensive (how can they spend 300$ if they can't even afford a 5$ shareware ), but considering the fact that IDA is made for a more professional context (e.g. security, antivirus, as has been said before) I think it's an adequate price.. It's also a very special tool, as the majority of computer users doesn't even know about disassemblers. Thus the number of sold licences will be accordingly small, demanding a higher price.
I also understand that software vendors refuse to give support to people that use non-licensed software (this includes demo software..). Man big companies selling professional software only give support to customers having paid for support.

But this is a wrong attitude. And it's not true that this tool is especially used for security. Me for example, Im using this to find out how Windows API calls work, what they do and so on.
I added many features in my application because I found out how some thinks work in windows. On example is windows autologon without using plain text registry key "DefaultPassword". I disassembled TewakUi for this purpose and found the solution there.
