I've got

Pentium 120mhz
32 MB RAM
Diamond Stealth DRAM 64 video card (S3 Vision864) (apparently VESA version 1.02, all I know is it's not great.)
Vibra16 Sound Blaster 16(compatible?)
Some random CD-RW drive that works just fine with oakcdrom.sys
MS-DOS 6.22
and of course, Windows 3.1

Attempting to install SimTower in Windows, it gets to 55% and says:
"Setup ran out of memory while copying! Terminate any running applications and try again."

I ran memmaker and told it to go ahead and save some for Windows, but that didn't help.
Diamond's InControl Tools are down in my lefthand corner, but shutting them down doesn't help (I'd like to get rid of them too but don't know how.)
Let's see if I can type out my current config.sys and autoexec.bat (after running memmaker)

Config.sys

DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE NOEMS WIN=ED00-EFFF WIN=EA00-ECFF
BUFFERS=40,0
FILES=40

LASTDRIVE=E
FCBS=4,0

DEVICEHIGH /L:1,25904 =C:\VIBRA16\DRV\VIBRA16.SYS /UNIT=0 /BLASTER=A:220 I:5 D:1 H:5

DEVICEHIGH /L:1,40800 =C:\OAKCDROM.SYS /D:MSCD001
DEVICEHIGH /L:1,12048 =C:\DOS\SETVER.EXE

Autoexec.bat

SET SOUND=C:\VIBRA16
SET BLASTER=A220 I5 D1 H5 P330 T6
SET MIDI=SYNTH:1 MAP:E
C:\VIBRA16\DIAGNOSE /S

C:\MOUSE.COM
LH /L:1,27952 C:\MSCDEX.EXE /D:MSCD001
@ECHO OFF
PROMPT $p$g
PATH C:\DOS
SET TEMP=C:\DOS

Boy I hope that's enough information to help.
