WOWEXEC problem when I try to install an application

I have tried this solution and when I type "sysedit" in run, the "WOWEXEC"
fault comes up,, what next??? I am trying to re-install my printer and cannot
get past this error to do so. Please help if you can. thanks

When a WinXP Home computer runs 16-bit applications it produces the following error
message: -
WOWEXEC caused a General Protection Fault in module MMSYSTEM.DLL at 000A:0032

WOWEXEC is short for "Windows on Windows Execute" and is a helper program used to run
16-bit applications under NT and XP.

A 16-bit program can give this error message when WOWEXEC is already running when the
16-bit program is started.

Make sure that WOWEXEC is not left in memory when a 16-bit program is closed.
To do this:
1. Log in as the administrator.
2. Run Regedit.exe (in \Windows).
3. Go to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WOW
4. Look for the entry DefaultSeparateVDM, and change it to Yes.
5. Close Regedit.

Another possibility is that the path name to the 16-bit program is longer than 128
characters. To solve this problem relocate the program on a path with a shorter name.

Note you can save the registry key first by:
On the File menu, click Export.
In the File name box, type SaveKey, and then click Save.
Or create a system restore point prior to editing.
Note: If the registry key is not there, you can simply create one by going edit>new.

Thanks Taurarian, but I already tried to go to regedit and I did change it to
yes, but no luck, Could you possible step me through the other idea you had,
I also tried another idea someone gave me which I had to run sysedit, which
prompt me to insert my XP disc, but also no luck, it said I am running a more
current version of xp and then closed. Im so frustrated!!, Thanks for your
help

Just some other things to consider to see if relevant to your situation

I know this thread is old, but having had the problem myself and figured it out with hints from other forums, users should know there is a likely culprit in the Nero Scout when you have installed Nero Essentials 7.
Kill the startup process NMBgMonitor and reboot. You will then be able to install applications again, and also get rid of the wms idle error on shutdown.
