Tried to download the Windows Monitor x64 for my Windows Server 2008 R2.

After downloading Windows claims that "The signature of PCMonitor_x64.msi is corrupt or invalid" and would not let me install the MSI file.

 

Never had such a warning from another program that I have installed, so I hesitated to install that agent.

Is it me or has the file a problem?

This seems to be a recent IE issue:

We could not reproduce this issue, could you please try again? If you still have an issue use a different browser.

Solved!

I found out it was in issue with the installed root/intermediate certificates of Windows. An intermediate authority was missing. After I installed that certificate, it worked.
