I know all about cache screanshot and all.But it prevent a basic windows user from getting it.
Thanks will try.

yes, you are missing something
have installed, activated and tested - works just fine
check that you have unpacked module correctly
please note that Zip file is somewhat confusing - there are module.info in the root and inside norightclick folder
you need to copy norightclick folder from the zip into modules folder and not a whole ZIP content

Maybe now i screw something because before whit the full file it was able to install and was on top of the list.
now it's where it should be in list but the square don't stay green.

Thanks.
Work fine now,had to uncheck all module then reselect all to activate it.
nice support thanks again.
