You have to use this program in DOS !!! No DOS-Box, no virtual mode device manager ! You'll need an Extended Memory Driver though, HIMEM.SYS.
If you still should use Windows 3.1 (or WfW 3.11), you normally just have to leave Windows - as long as you didn't load EMM386, QEMM or any other virtual mode device manager in config.sys. If you should have, ctcm will tell you. The probably easiest way to run ctcm is to create a boot disk with nothing in the config.sys. You won't need a autoexec.bat, but if you're smart, you put the line "C:\ctcm\ctcm.exe" as only line in the autoexec.bat, where "C:\ctcm\" has to be replaced by your ctcm directory - wherever you store it on your hdd. In this case the computer will boot and straight away run ctcm.
In case you are a Windows 95 user (like me), you either anyway have a dual boot option to boot into old DOS, or you haven't (tsts !!!). If you should have the boot menu, you just choose Start in MSDOS Mode. If not, you either press F5 continuously after the BIOS POST, cause that'll get you into the boot menu, or you can get into MSDOS mode from Windows 95, via choosing Start Computer in MSDOS Mode from the shutdown menu or you'll also have to create a boot disk as described above.
The real cracks have got a boot menu for their old DOS (as myself of course ;-) ) and certainly have an option to boot with only the XMS driver, as you need it for lots of the modern games nowadays. In this case it's easiest of course, you boot this way and run ctcm, basta.
The results should speak for themselves, after all I eventually translated that nice little program ;-).
There are quite a few command line options for ctcm, but these I will explain at a later stage - or translate the readme file. You wont need any command line options for the results I would like you to send back.
