My environment: win8 64bit, vs2010, I follow every step in the tutorial but my own dll plugin just can't be installed, I have also installed WiX toolsets and made a msi file, but it simply do not work...
(1) I do all the work with prompt(privileged ) cmd.
(2)My files are shown in below

(3)firefox about:plugins page do not contain my dll plugin after my msi file installed..
(4) failed ..

So what is going on here?
