RunTIme Error 21 (XP Sp2)

ok, bit of a compilation of some other I have seen but it worked for me. First, switch off system restore, then boot up in safe mode. There were 4 places I found the offending file, which on my computer masqueraded as an Intelli Mouse file (whatever that is). First on a simple search, for *japi*.* files where it shows up as ncsjapi32.exe, it says its in System32/spml folder but that folder doesn't show up in explorer, there were also 2 other files in the folder, so do a search by date for the last week and you will find all 3. Second was using (yes another program to download) HijackThis, which shows all the open programs, sort of like a control Alt Del, but better, and gives you the option to delete the open programs under "fix it" in the bottom left. The third place was under the start menu, and "run" any type in MSCONFIG, where under the start up programs it again shows up. And 4th, again in start "run"under the "regedit"under HKey current users/software/microsoft/windows/currentversion there are run and runonce and it shows up in both.
So have all 4 open, then unclick the program in the configsys, so that it doesn't automatically start up, the deleted it in the regedit, and the hijackthis (sometimes 2 or 3 entries here so don't be fooled), and on the search (plus the two other files that were in the same folder & the folder). Then reboot again in safe mode.
If it seems to have fixed it, check all the above places to make sure they are all gone. Hope it works, if not sorry, it did for me

1. Boot up in "Safe Mode", but choose the one with "With Command Prompt"

2. Once you have the Command Prompt, change to directory by typing:
CD c:\windows\system32\splm + ENTER. Or d: or whatever your windows directory is called.

3. Change the attributes of the files in this directory not to be hidden:
ATTRIB *.* -H

4. If you go DIR + ENTER you will see 3 files
kbdsapi.dll
lmfunit32.dll
ncsjapi32.exe

5. DEL *.* + ENTER should delete them.

Your problems are over !

But go and delete the Registry entries, as in ATony's suggestion.

I have used system restore to remove this problem, setting computer to an earlier date. But you have to be fast when attempting to get to system restore or the runtime errors will freeze the screen. As soon as the icons load click programs, accessories, system tools and then restore, BUT YOU HAVE TO DO IT QUICKLY!
