To get started, install Windows 7 SP1 if you haven't already.
Otherwise, download the service pack 1 of Windows 7 from the Microsoft Update catalog and install it in the virtual machine.
If you click on the "KB4474419" link referenced on the VMware site, you will arrive on a page : SHA-2 code signing support update ...
As you can see, this update will add support for the SHA-2 algorithm for code signing.
This will allow Windows 7 to be able to correctly check the signature of the various drivers that will be installed by VMware Tools in your virtual machine.
To download this update, you can use Windows Update or download it manually from the Microsoft Update Catalog by clicking on this link : KB4474419.
On the site that appears, sort the list by date of the last update to find the most recent version of this Windows update and download the one adapted to the architecture of Windows 7 that you have installed :
Once you click on the "Download" button, you will have a small window like this with a download link.

To transfer this update to the virtual machine, you have several options :
Indeed, drag/drop and VMware Workstation shared folders don't work for the moment since VMware Tools are not installed in your virtual machine.
Launch the downloaded file and a window will appear telling you : Security Update for Windows (KB4474419).
Wait while this Windows update is installed.
Restart the virtual machine after its installation is complete.
The "Configuring Windows updates" message appears while restarting the virtual machine.
Now, you can install VMware Tools by clicking on : VM -> Install VMware Tools.
Wait while the VMware Tools install.
As expected, the installation completes without any warning and without any error.
Once the virtual machine has restarted, don't forget to activate Windows 7 aero, by right-clicking "Personalize" on the desktop, then clicking on the "Windows 7" Aero theme.
