I am stuck with sub-system setup was interrupted, and whatever option I select it keeps coming back to the same 4 options without allowing me to boot to Windows. Please help.

I have exactly the same problem and I can't get out of it. I'm on my laptop at the moment because I can't get my desktop to work. It keeps looping back to those same 4 options no matter what I do.

The last thing I expected when I downloaded this program was for it to destroy my computer. Not a happy camper.

Evil program, destroyed my computer and won't start , i can't even start safe mode

I was given two options to remove the software by the software support:

FIRST OPTION
Please try the following way. 1. Reboot your computer. And press Ctrl+F8 hot keys.2. Time is: just after you start your computer and before the subsystem modes selection interface appears.3. Way is: Hold on Ctl key, meanwhile press F8 again and again, until you can see some options.4. Then choose the last option, Remove SubSystem, and then Enter.5. You will be required to provide the password, please enter 12345678, and then enter key.6. You will get the message that the program has been removed.7. Then reboot your computer.

SECOND OPTION WHEN THE ABOVE DID NOT WORK
Seems that the program is not compatible with your computer.
Now, please try another way to uninstall it:

Find one DOS bootable CD or USB, and boot into the DOS environment;
Run fdisk /mbr command;
Nothing will happen unless you get error message, just reboot your PC after the running of the mind;
The program will completely removed.

Second option worked for me. I booted with a DOS6.22 version CD, which I created from the following site:
