You need to get some one who does know how to use computers to help you then. This requires you to go into your registry and remove the bad reference. I only suggest this be done by some one who knows how. Do you have any friends that can help you?

NTVDM stands for NT Virtual Dos Machine. It is the virtual DOS environment that allows you to some SOME 16 bit DOS commands on a 32 bit Windows system.

Setup.exe appears to be a DOS application and is trying to execute a DOS instruction that the NTVDM does not allow. This usually means something the is trying to address the hardware directly like Int21. It has probably been left over from a failed installation attempt.

Someone with knowledge of the registry will get rid of it in seconds.

Might to see if that actual file exists. It may not be caused by a registry entry also. Find that temp folder and setup.exe file and rename it at least to setup.old and reboot.

Might look at msconfig too. It might show up there.
