Download and Install IBM i ACS (Access Client Solutions)


Feb 22

Client Access is DEAD – get over it!

Client Access was much reviled, much loved and mucho mucho confusing for users of AS/400, iSeries and the newer IBM i Power Systems. As it evolved and got rebranded as IBM i Access with new releases of the operating system, many people from the technical end of the spectrum just kept on calling it “Client Access” because all of old grey haired “400” users know what that is.

IBM i Access for Windows delivers TCP/IP connectivity to users running a variety of Microsoft® Windows® operating systems. IBM i Access for Windows offers an all-inclusive client solution for accessing and using resources from your Windows desktop. It includes 5250 emulation, access to DB2 Universal Database® (UDB) for IBM i through its Data Transfer, and utilizes IBM i NetServer for working with the IBM i Integrated File System and printers. It also has a variety of middleware for using and developing client applications to access IBM i resources; and Navigator for i, the i5/OS GUI, for administering your IBM i.

IBM does not plan to support IBM i Access for Windows on operating systems beyond Windows 8.1. The replacement product is IBM i Access Client Solutions

So now it’s finally officially retired.

Lets meet the new kid on on the block


IBM has now made this a chargeable product at the fumingly expensive price of $355 per user per year. Hashtag OUCH.

So, the rest of this blog, where I talk about downloading it for free is out of date. But, if you do have an IBM SUPPORT license then you can go and grab it, so read on.

If you don’t have a license, or you’re a lowly freelance IBM i Developer (like me) then I would recommend checking out either RDi and its integrated 5250 Emulator (which you need to pay for but its worth it) or use some other combination of free terminal emulator software.

IBM i ACS (Access Client Solutions)

IBM have never had any idea about how to name things. What a stupid name. Why not just call it “IBM i Navigator” or something simple? *sigh*

Anyway… must stop moaning about naming conventions so lets go and download your copy of IBM i ACS from IBM

(make sure you read the quickstart quide)

Download the File and extract it to a temporary unzipped-folder on your PC.

Using Windows Explorer goto \\unzipped-folder\Windows_Application folder.

  • To install the 32 bit version for the current user, double-click on install_acs_32.
  • To install the 64 bit version for the current user, double-click on install_acs_64.
  • To install the 32 bit version for all users on a multi-user PC, double-click on install_acs_32_allusers.
  • To install the 64 bit version for all users on a multi-user PC, double-click on install_acs_64_allusers.

If this is a new installation, there will be several prompts that will help you customize the initial installation. If a license agreement appears, accept it. If this is an upgrade, the previous settings will be preserved.

During the install you will be asked which options to install. Choose all of them 🙂

When the install has finished, a completion message will be displayed.

A successful single-user install will copy the application to: /Users/user_id/IBM/ClientSolutions/

A successful multi-user install will copy the application to: /Users/Public/IBM/ClientSolutions/

Launch IBM i ACS

Double-click the “Access Client Solutions” icon on the desktop.

Having said that, and having used ACS for several months now — it’s a uge improvement over the old Client Access Windows Software. It’s smoother, faster and the green screen and IFS integration is much better. If you are nervous about installing it on your desktop then this might help :
