Contrary to popular belief, VMware still provides legacy downloads—but only to registered users with valid entitlements.
Use these commands (example for build 1331820 – find actual hashes on VMware KB 2096141):
Windows (PowerShell):
Get-FileHash -Algorithm SHA256 .\VMware-VMvisor-Installer-5.5.0-1331820.x86_64.iso
Linux/macOS:
sha256sum VMware-VMvisor-Installer-5.5.0-1331820.x86_64.iso
If the hash doesn’t match a known official source, destroy the ISO immediately.
Many vendors host their own customized versions of ESXi 5.5 for their hardware.
✅ Pro Tip: Even without an active support contract, Dell and HPE often allow downloads if your hardware is still under a base warranty.
Since the acquisition of VMware by Broadcom, the portal structure has changed. To access legacy binaries, you typically need an active support contract or a registered account.
Running an unpatched hypervisor is like leaving your server room door wide open in a high-crime neighborhood.
