The Lotus Notes Client 8.5.3 is a legacy version of the collaboration software originally released by IBM in December 2011. While it can be installed on 64-bit operating systems, there was no native "64-bit client" for Windows in this version; it was a 32-bit application designed to run on both 32-bit and 64-bit Windows platforms. Key Technical Context
Architecture: Version 8.5.3 remains a 32-bit application. It is compatible with 64-bit versions of Windows 7, but may require administrative tweaks to run smoothly on newer OS versions like Windows 8 or 10.
Release Purpose: This version was primarily a "Maintenance Release" focused on bug fixes—addressing approximately 1,200 known issues—along with minor enhancements to the mail sidebar and search functions.
Current Status: This version is end-of-life and no longer supported by IBM or HCL (the current owner of the brand). Users are generally encouraged to upgrade to HCL Notes 9, 10, or higher for modern OS support and security updates. Download and Installation Information

I understand you're looking for a download link for Lotus Notes Client 8.5.3 (64-bit). However, I need to provide some important context and a realistic path forward.
The Short Answer:
You cannot download Lotus Notes 8.5.3 legally from any official IBM/HCL public link anymore. That version is over a decade old, and IBM sold Lotus Notes/Domino to HCL Technologies in 2019. HCL now supports only versions 10, 11, 12, and 14.
The Story Behind Your Search
Back in the early 2010s, Lotus Notes 8.5.3 was a popular enterprise email and collaboration client. Many large corporations, banks, and governments ran their internal systems on Domino servers with Notes clients. The 64-bit version was specifically for Windows 7/8 and later, addressing memory limits of the 32-bit client.
But here’s the reality today:
What you can actually do:
| Your goal | Feasible action | |-----------|----------------| | You have a valid license from an old employer | Contact their IT dept — they may have an internal installer archive | | You need to access an old NSF file | Use HCL Notes 14 (free 90-day trial) — it opens legacy NSF files | | You’re troubleshooting a legacy system | Run the 32-bit version of 8.5.3 (more common), but only inside an isolated VM without internet | | You just need old Notes functionality | HCL offers a free Verse or Nomad web/mobile client for Domino servers |
If you still insist on finding 8.5.3 64-bit:
My recommendation:
Download HCL Notes 14 from the official HCL site (free trial). It will read your old 8.5.3 NSF files without issue, runs natively on 64-bit Windows 11, and is secure.
Would you like step-by-step guidance on using HCL Notes 14 to open an old NSF file from Lotus Notes 8.5.3?
Getting the Lotus Notes 8.5.3 client to work on a 64-bit system is a common task for legacy enterprise environments. While this specific older version is essentially a 32-bit application, it is designed to run natively on 64-bit operating systems like Windows 7, 8, and 10. Key Version & Download Information
Version Status: Lotus Notes 8.5.3 was a major maintenance release that introduced stability fixes and small feature enhancements.
Architecture: There is no native 64-bit version for the Lotus Notes 8.5.3 client; the first official 64-bit client was not released until version 12.0.2. For version 8.5.3, you must use the standard 32-bit installer, which runs under the WoW64 (Windows-on-Windows 64-bit) subsystem.
Current Availability: Since IBM sold the product line to HCL Technologies in 2019, downloads for older versions are primarily found on the My HCLSoftware (MHS) portal. Recommended Setup for 64-bit Windows To ensure the best performance on a modern 64-bit machine:
Install Fix Pack 6 (FP6): This is highly recommended for 8.5.3 as it specifically adds support for Windows 8.1 and includes critical stability fixes for modern environments.
JVM Tuning: To improve speed on 64-bit systems, you can increase the memory allocated to the client by modifying the jvm.properties file, changing -Xmx256m to a higher value like -Xmx768m.
Modern Alternatives: If you are not restricted by legacy server requirements, consider upgrading to HCL Notes 12.0.2 or later, which offers a true native 64-bit client and better integration with current hardware.
