Remove the extra space here.

This isn't exactly what I meant. C:\Windows might not even exist on
NT4/Win2000 and the temp directory might not be in %WINDIR%\temp. You
should use GetTempPath instead. (Hard-coding C:\ is also something to
be avoided if at all possible.)

(try 2)version: check for out of memory when VerInstallFileA/W converstion. (response to coverity 635)

Whoops on the whitespace.

The paths are irrelevent.  They are intentionally pointing at a file and 
location that is not existing.  Should I change the paths to express 
that more explicitly;  something like: "D:\oes\not\exist" ?

Sure, that would work. That way we can be sure it won't give us
different results on different test machines.
