I have been trying to download a legal medical software program for my consulting business that I hope to start soon and everytime I try to install it I get an error message that reads 16 bit subsystem C:\Windows\Systems 32\autoexec.nt and then it says System file not suitable for running MS-DOS and Microsoft Windows Application. I know some about computers but not anything like this. I have a presario Compaq R3000 notebook with Windows XP, I have talked with HP who I bought it from and they had me put the operation disc in to restore files as they said I had corrupt files but that didn't work. Any suggestions? It came with Window XP so I don't have a disc to reinstall it with and I can't send it back to the factory because I'm also taking an online course so i need it to bad. Any help anyone an give will sure be appreciated.
