Hi,
Unfortunately, the official links are broken (We will try the best to report this issue and hope it could be fixed soon).
When we download a management pack (commonly .msi file) and install it (by double-clicking), it will extract the .mp/.mpb files in the c:\program files (x86)\system center management packs folder.
After that, we may import the .mp/.mpb files by browsing the folder above.
At present, one possible solution is to find a working computer and copy the folder to desired computer.
Hope the above information helps.
