Fatal error when installing Management Console

Originally I have 11.5 on my PC (Win 7 x64 SP1) and it works fine.

I want to update it to 11.7, when I tried to install 11.7 Management Console, it shows

I find the "answer" in here

It says

------------------------------------------------------------------------------------------------------------------------

And this error:

Windows Popup shows message:

"File "C:\WINDOWS\Installer*.msi" was rejected by digital signature policy"

Cause

The issue is caused in Microsoft Installer. This issue occurs if the Windows Installer process has insufficient contiguous virtual memory to verify that the .msi package or the .msp package is correctly signed.

Solution

The solution for this issue, you will find in the Microsoft Knowledge Base in this article.

But I don't have the sympotom shown in red words above.

I tried to go back to 11.5, but the same error occured during 11.5 management console installation.

I also tried "abr_cleanup_h.exe" (cleanup tools for Acronis backup), no lucky.
