When its almost done installing onto my computer, it says:

[16 bit windows subsystem]
C:\WINNT\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsof Windows applications. Choose 'Close' to terminate the application.
[close] [ignore]

What the heck do i do???

from PhotoShop? if you have PS, why are you installing DrawPlus?

generally that error means that the autoexec.nt is either missing or corrupted.

if you have the install disk for your OS, run the CD and copy the file to the System32 folder. i don't recommend doing this if you don't really know what you're doing.
