Possible Solution:

Edit the config.nt file in the C:\windows\system32 directory to read:

EMM = B=4000 RAM 
dos=high, umb 
device=%SystemRoot%\system32\himem.sys 
files=40 

Note the spaces in the EMM line carefully - one either side of the first = and before RAM, none with the second = 

Also make sure there is a line in your autoexec.nt file (C:\windows\system32 directory) that reads: 

lh %SystemRoot%\system32\dosx 

The error statement which the user where I got this info stated insufficient conventional memory. This fix should give 612k of conventional memory, which seems to be the maximum possible.

copy \windows\repair\autoexec.nt   \windows\system32\autoexec.nt

Sounds like the file was corrupted.

Thanks for you comment.

I resolved the same problem with your tip. My file was wrong. There was a lot of comment's line without "REM", so, I just put the file as you recommended and I installed the aplication.

This still didn't solve my problem. My AUTOEXEC.NT file reads currently:

 

@echo off

1h %SYSTEMROOT%\system32\mscdexnt.exe

1h %SYSTEMROOT%\system32\redir

1h %SYSTEMROOT%\system32\dosx.exe

SET BLASTER=A220 I5 D1 P330 T3

 
and my CONFIG.NT file reads:
 

EMM = B=4000 RAM

dos=high, umb

device=%SYSTEMROOM%\system32\himem.sys

files=40

 

But I still get the error message:

 

The Win15 Subsystem was unable to enter Protected Mode, DOSX.EXE must be in your AUTOEXEC.NT and present in your PATH.

 

so what else should I do?

I have done all of the above also and still I also get the same error messege. I am trying to install a PC game, plus I was getting this error messege when i try to update my DirectX and several other programs.   Earlier on , I had infected my pc with either a virus or some spyware that had my whole desktop black out and had a click on link that covered the whole screen asking if I wanted people to view my personal stuff and if not to click here to remove some spyware, those anuses.  Well i took my pc to a freinds and house and he removed alot of junk manually , and now when i go to install a few programs I also get the same exact messege that has been pleaguing everyone else.
