This is a bug in the program. Intel is working on a fix. In the meantime, if you install something and it comes back and say it still needs to be installed, then just ignore this notification.
No, no mistake. The issue is that, in any packages that contain multiple drivers or multiple versions of a driver, the version numbers for these drivers will not match the version number of the overall package. The tool ends up comparing a driver version number to a package version number and this usually results in it thinking the package needs to be installed when it doesn't. As I said, Intel is presently working on a fix for this issue.
