in thread Does Inline::CPP module works with VS 2008(vc 9.0)

This is the same problem you seem to be facing when using/installing Win32::GuiTest. I recommend, again, checking your module paths and installation paths and generally following the same steps you've taken to solve the problem with Win32::GuiTest. Most likely, the cpan you're running is not the cpan associated with the perl you're running.
