Packing my software

[dirso]

Hi,

I made a MS-DOS application (using Borland C++ 3) and somebody find out how to distribute it for other clients. To do that the open my exe with an hex editor and change the HD's serial. My only solution is to Pack my software, so the hex editor would be useless. I tryed to use PKLITE, but the available version is for win32 only...
Does anybody know some packer for this kind of application? Better if free

Thank u very much,
Dirso.

Packing your software will not solve your problem. I'm assuming that your program would need to be unpacked in order to be used. Once this happens, you have the same exposure to piracy you originally complained of. Your time would be better spent looking at copy protection schemes. Note, however, that even copy protection schemes are not 100% fool-proof. Welcome to the world of software development...

Actually, the software doesn't need to be unpacked before used. This kind of packers compacts the exe and adds a header enough to let the new executable "runnable" itself.
