Could be the 16 bit subsystem from Windows that is causing the error.
Lets see if this solves it:
1) Goto
THIS PAGE2) Download the HijackThis Log Analyzer
3) Install it
4) In the installation folder there is a file called winrep.zip
5) Extract the contents of that file to %windows%\system32, ovrewrite excisting files
6) See if the problem is solved.
ps: after doing this, you can ofcourse keep/remove the util as you like.
