Open up a command window and try launching it manually from the command line. Chances are you will get an error about not being able to setup 1GB heap. We used to get that all the time. The answer is generally to start it first and get it running before Outlook, Jabber, Webex or any other program you can determine likes to fragment the heap space available in Windows. ACS needs a full contiguous 1GB to startup, if it can't get it, it pukes.

We found that even after closing all the applications, you can still have the heap too fragmented to start ACS, so we generally reboot but a logoff might work.

We have also noted that since moving to Office 365 and keeping the number of conversations open in Webex, we have this issue less often.

Subject: ACS Clients won't launch from the desktop


I'm having trouble getting ACS to run in Windows 10.

I have IBM i Access Client Solutions installed and running.
I setup my system with an IP address.
I configured my clients in Session Manager.
The clients will launch from Session Manager.
The clients won't launch from the Desktop.

I have jre1.8.0_333 installed.

In IBMi Access Client Solutions under the Tools tab I selected File Associations:
I put a checkmark in:

I'm running Windows 10 ver. 20H2

Does anyone have any idea why my clients won't launch from the desktop?
