On my PC, i'm getting very strange problem while i try to install/uninstall SilkTest Version5.0.3. When i try to install/unintall the SilkTest it gives a message "The win16 SubSystem was unable to enter Protected Mode, DOSX.EXE must be in your AUTOEXEC.NT and present in your path" After this error message i'm not able to install the SilkTest. May i know why this problem has occured on the system any remedial action for the same? I think if this problem doesn't solve then only option i have is to format the system and that is the last thing i want to do. So pls help me ASAP.
