The VMware vSphere Client 5.5 is a legacy desktop application (often called the "C# client") used to manage ESXi 5.5 hosts and vCenter 5.5 environments. While Windows 10 is not officially supported for this version, it can typically be installed with specific compatibility adjustments. 🛠️ Prerequisites & Compatibility
Before installing, ensure your system meets these specific legacy requirements:
Operating System: Windows 10 64-bit (Professional or Enterprise editions are recommended).
.NET Framework: Requires Microsoft .NET 3.5 SP1. If not enabled, the installer will attempt to install it or fail.
Hardware: Minimum 500 MB RAM (1 GB recommended) and at least 1.5 GB free disk space. 📥 How to Download You can obtain the installer through the following methods:
Direct from Host: Navigate to your ESXi host's IP address in a web browser (e.g., https://192.168.1.50). A link to "Download vSphere Client" is typically provided on the landing page.
Broadcom/VMware Portal: You can find official installers on the Broadcom Support Portal (formerly VMware). You must log in with a registered account to access downloads for vSphere 5.5.
Direct Link: Known official builds include versions like VMware-viclient-all-5.5.0-1993072.exe. 🚀 Installation Guide for Windows 10 vmware vsphere client 5.5 download windows 10 64 bit
Follow these steps to avoid common "Access Denied" or .NET errors:
Enable .NET 3.5: Go to Control Panel > Programs and Features > Turn Windows features on or off. Ensure .NET Framework 3.5 is checked and installed.

⚡ Pro Tip: If you get a "Visual J# 2.0" error (Error 1603), try installing a newer version of the vSphere Client (like 6.0) first to lay down the necessary system files, then run the 5.5 installer again. ⚠️ Important Limitations VMware vSphere Client - Oracle Help Center

I understand you're looking for the VMware vSphere Client 5.5 for Windows 10 64-bit. However, I need to give you an important heads-up:
Critical Note:
VMware vSphere Client 5.5 is very old (released 2013) and not officially supported on Windows 10. It may install but can be unstable, have display/network issues, and lacks security updates. The modern replacement is the HTML5 vSphere Client (via web browser) or VMware Host Client.
That said, if you still need the legacy vSphere Client 5.5 (a Windows-only .exe):
ESXi 5.5 update 2 introduced a basic HTML5 host client. Point your browser to https://<ESXi-IP-Address>/ui. It lacks many advanced features but works flawlessly on Windows 10.
Running vSphere Client 5.5 on Windows 10 64-bit introduces risks:
Recommendation: Isolate any Windows 10 machine running vSphere Client 5.5 on a management VLAN with no internet access.
