You must install these patches in a specific order to avoid package rejection: Launch and install (the SSU) first. Launch and install KB4474419 (the SHA-2 update) second.
System administrators frequently encounter this roadblock when deploying or updating virtual machines running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1) .
Here is the story behind that specific article number and why people are often looking for "free" access to it.
If you're interested in learning more about VMware, virtualization, and KBVMware, here are some additional resources you might find helpful:
Once the virtual machine has rebooted after applying the updates, try installing VMware Tools again. With the SHA-2 code signing support now present in the OS, the driver signature verification will succeed, and the installation should complete without errors. kbvmware s article 78708 free
VMware KB Article 78708 is a vital piece of the puzzle for anyone managing a virtualized infrastructure. By offering this information for free, VMware empowers administrators to maintain secure and efficient environments. Whether you are dealing with a minor bug or a major configuration roadblock, the Knowledge Base remains your first line of defense.

If you tell me what KB 78708 is about (e.g., “fixing VM disk consolidation error”), I can write a full, original blog post that solves that problem without copying VMware’s proprietary content.
Before applying specific SHA-2 updates, your legacy Windows OS must be running its final Service Pack lifecycle stage. Right-click and select Properties .
Modern virtualization requires higher security standards. As outlined in the release notes for VMware Tools 12.4.0 , failing to implement SHA-2 support means your VM cannot verify the authenticity of the drivers provided by VMware, resulting in a blocked installation.
Resolving this issue is completely free and relies entirely on pulling official, free patch files from Microsoft’s update catalogs. To bypass the restriction and get VMware Tools running smoothly, follow these operational steps: Step 1: Verify Guest OS Prerequisites Here is the story behind that specific article
Modern versions of VMware Tools (version 11.1.0 and newer) comply with this standard, meaning all drivers packaged within the installer are signed using SHA-2. Legacy operating systems lack the native ability to verify SHA-2 signatures out of the box. These systems include: Windows Server 2008 R2 SP1 Windows Server 2008 SP2
: Set up alarms in vCenter to notify you when partition usage exceeds 80%.
The primary solution, as documented in KB 78708, is to that add SHA-2 code signing support to legacy Windows systems.
Newer VMware Tools versions (11.1.x and later) bundle drivers that are signed with SHA-2. When you try to install these drivers on an unpatched Windows 7 system, the operating system's driver signature verification process fails because it doesn't recognize SHA-2 signatures. This failure triggers the "must be installed manually" error and halts the installation.
When Microsoft changed its driver signing policy to exclusively use the SHA-2 algorithm, older legacy Windows systems could no longer verify the integrity of newly packaged VMware drivers. This results in installation aborts, broken display drivers, or broken network interfaces inside your guest operating system.
