Side-by-side configuration is incorrect reported as permission denied

I use Cygwin a lot. And I kick off Windows processes a lot. Recently 
I've been having a problem with my system but from Cygwin all I see is 
"permission denied":

    Ltsdo-adefaria:cd /cygdrive/c/Program\ Files/IBM/RationalSDLC/Clearquest
    Ltsdo-adefaria:ls -l clearquest.exe
    -rwxr-xr-x+ 1 Administrators clearusers 245760 Jun  2  2011
    bash: ./clearquest: Permission denied

However if I use cmd the real error message comes out:

    Ltsdo-adefaria:cmd /c clearquest
    The application has failed to start because its side-by-side
    configuration is incorrect. Please see the application event log or
    use the command-line sxstrace.exe tool for more detail.

I know that this "side-by-side configuration is incorrect" is a 
configuration error on my machine and I need to fix it, but shouldn't 
Cygwin's exec(2) report the "side-by-side" error instead of the more 
erroneous "Permission denied" error?

Why do you press harder on the buttons of a remote control when you know 
the batteries are dead?
