Thanks N.Scott.Pearson! Could it be that Intel engineers just mistake files in the zip archive?
Please take a look at that bug: Unable to install Intel Management Engine 188.8.131.5260 on NUC7i7BN with Win10 x64
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.
