Knowledge Base (KB) article from VMware (now Broadcom) is a critical technical document addressing installation and upgrade failures of VMware Tools on legacy Windows operating systems. Broadcom Community Core Issue: SHA-2 Code Signing Requirements
Starting in December 2019, Microsoft transitioned exclusively to the SHA-2 algorithm
for signing Windows drivers. Consequently, legacy systems that lack SHA-2 support fail to verify the digital signatures of modern VMware Tools drivers, leading to installation errors or non-functional devices. Broadcom Community Affected Operating Systems The article primarily concerns the following versions: (Service Pack 1) Windows Server 2008 R2 (Service Pack 1) Windows Server 2008 Broadcom TechDocs Recommended Solutions
To resolve these failures, administrators must ensure the guest operating system is updated to support SHA-2 signing before attempting to install VMware Tools version 11.1.x or newer Broadcom Community Apply Microsoft Updates
: Install the specific Windows updates (such as KB4474419 and KB4490628) that add SHA-2 code signing support to these legacy versions. Version Compatibility
: If updates cannot be applied, users must use an older, compatible version of VMware Tools (typically version 11.0.x or earlier) that still utilizes SHA-1 signing. Verification
: Check that the "Install VMware Tools" menu item is not grayed out and that the digital signature of the installer is recognized by the guest OS. Broadcom Community

VMware Knowledge Base article 78708 states that Windows 7 SP1 and Windows Server 2008 R2 SP1 guests require the Microsoft SHA-2 security update (KB4474419) to install VMware Tools 11.x and later, as shown in studies and community discussions. A potential feature to address this is an automated pre-check that scans for this specific KB, identifies the guest OS, and prompts the user to install the update if missing.

Understanding VMware KB 78708: Resolving VMware Tools Installation Issues on Windows 7 kbvmware s article 78708 free
If you are trying to install or upgrade VMware Tools on a Windows 7 or Windows Server 2008 R2 guest operating system and encountering errors like "Setup failed to install driver automatically," you are likely running into the issue documented in VMware KB 78708.
This article provides a comprehensive look at why this happens and how to fix it for free using official Microsoft updates. The Root Cause: SHA-2 Code Signing
In late 2019, Microsoft transitioned its driver signing process to use the SHA-2 algorithm exclusively, phasing out the older, less secure SHA-1. Modern versions of VMware Tools (starting with version 11.x) are signed with SHA-2.
Because original installations of Windows 7 SP1 and Windows Server 2008 R2 SP1 do not natively support SHA-2 code signing, they cannot verify the digital signatures of the new VMware drivers. This causes the installer to fail when attempting to load essential components like the VMXNET3 network driver or the SVGA graphics driver. Symptoms of the Issue You may notice the following when attempting an install:
A Windows Security warning stating: "Windows can't verify the publisher of this driver software".
The VMware Tools installer displays: "Setup failed to install xxx driver automatically. This driver will have to be installed manually".
The installation rolls back, leaving the VM with basic graphics and limited connectivity. How to Fix It (Step-by-Step)
To resolve this, you must manually install two specific Microsoft updates that add SHA-2 support to your guest OS.
Verify Service Pack 1: Ensure your Windows 7 or Server 2008 R2 installation has Service Pack 1 (SP1) installed, as it is a prerequisite for the following patches.
Download KB4474419: This is the primary update that introduces SHA-2 code signing support. It is available for free via the Microsoft Update Catalog.
Download KB4490628: This servicing stack update is often required to properly handle SHA-2 signed updates. Install and Restart: Install KB4490628 first. Install KB4474419 second. Restart the virtual machine to apply the changes.
Run VMware Tools Setup: Once the VM is back online, you should be able to run the VMware Tools installation without any signature errors. Important Compatibility Notes
Version 12.x Requirements: For VMware Tools 12.2.0 and later, you also need the Microsoft Visual C++ 2015-2022 Redistributable installed in the guest OS.
Frozen Versions: VMware has "frozen" certain versions of VMware Tools for legacy operating systems. If you cannot update your Windows 7 guest to support SHA-2, you may need to use an older, "frozen" version of VMware Tools (like version 10.3.x), though this is not recommended for security reasons.
By applying these free Microsoft updates, you ensure your legacy virtual machines remain compatible with modern VMware environments while maintaining proper driver performance and security. VMware tools fail to install on Windows 7 Guest | Fusion

Title: Just a heads up on KB 78708 (VCSA Backup Issues)
Hey everyone,
Just wanted to share a quick win. I was running into issues with a VCSA backup failing intermittently. The logs were vague, pointing generally toward "snapshot creation failure."
After a bit of digging, I found VMware KB 78708 (free access, no login required for basic viewing).
The article breaks down the exact registry/config checks needed to clear out the stale snapshot references that were blocking the backup. If you are seeing errors like "Operation timed out" or "Snapshot creation failed" in your backup logs, give this KB a read. It’s much faster than opening a support ticket.
Hope this saves someone else a headache!
