Installing VMware Tools on legacy Windows systems requires manually updating to support SHA-2 code signing, which resolves driver verification failures when installing version 11.1.x or newer. Users must install Microsoft updates KB4474419 and KB4490628 to enable this support. For more details, visit Broadcom Knowledge Base. VMware tools fail to install on Windows 7 Guest | Fusion
Understanding VMware KB 78708: How to Free Up Space on Your VMware Appliances
VMware Knowledge Base article 78708 is a critical resource for system administrators managing VMware vCenter Server Appliances (VCSA). It provides a specific script and set of procedures designed to identify and remove unnecessary files that often bloat the appliance’s storage partitions. When these partitions reach 100% capacity, the vCenter services frequently fail to start, leading to management downtime. Why Your VMware Appliance Runs Out of Space
The vCenter Server Appliance is a Linux-based virtual machine with several dedicated partitions. Over time, these areas can fill up due to:
Audit and Syslog Data: Historical logs that haven't been rotated properly.
Old Patch Files: Leftover data from previous VCSA updates or installations.
Crash Dumps: Large core dump files created during service failures.
Temporary Files: System cache and temporary data that wasn't automatically cleared.
When the /storage/log or /storage/seat partitions hit their limit, the Postgres database or the vpxd service may crash, preventing you from logging into the vSphere Client. How to Use the KB 78708 Cleanup Script
The primary solution offered in KB 78708 is the execution of a automated cleanup script. This is much safer than manually deleting files via the command line.
Backup Your Appliance: Before running any cleanup script, take a snapshot of your vCenter Server Appliance.
Access the Shell: Log in to the VCSA via SSH or the VM console using root credentials. Type shell to enter the BASH interface.
Download/Locate the Script: The KB article provides a script (often named cleanup_vcsa.py or similar in later iterations). If your environment is offline, you may need to copy the script content manually into a new file on the appliance.
Execute the Script: Run the script with Python. It will scan the common directories for "safe to delete" files, such as old logs and temporary update files.
Restart Services: Once the space is reclaimed, you may need to restart the VCSA services using the command: service-control --start --all. Manual Cleanup Areas to Monitor
If the script does not resolve all issues, KB 78708 and related documentation point to several specific directories that often require manual intervention:
/storage/core: Look for large core.* files. These are memory dumps from crashed processes. If you don't need them for a support case, they can be deleted.
/storage/log/vmware/sso: Check for old localhost_access_log files that may have accumulated over months.
/storage/updatemgr: If you use Update Manager or Lifecycle Manager, old patches and metadata can consume significant space here. Preventing Future Disk Space Issues
To avoid recurring "disk space full" errors, consider the following maintenance steps:
Configure Log Rotation: Ensure your syslog settings are not set to "verbose" unless you are actively troubleshooting.
Monitor Disk Usage: Set up alarms in vCenter to notify you when partition usage exceeds 80%.
Regular Patching: VMware often releases updates that improve log management and automatic cleanup routines.
Increase Disk Size: If your environment has grown significantly, you can use the vSphere Client to increase the size of the virtual disks (VMDKs) attached to the appliance, then use the vpxd-service-control tools to expand the logical partitions.
By following the guidance in KB 78708, administrators can quickly restore functionality to their vSphere environment without needing to redeploy the entire management server. Always ensure you are viewing the most recent version of the article on the official VMware (Broadcom) Support portal for the latest script updates.

Understanding VMware KB 78708: Resolving VMware Tools Installation Issues on Windows 7
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
