ERROR: error invoking dialog: 20
Unable to run test authentication RSA Authentication Agent 6.1
No error messages logged.
Hour glass icon appears until the attempt times out.
Direct test auth prompter return wasn't OK or Cancel, but was: 20
|Cause||UIService.exe does not appear to be running in the task manager.|
To correct this issue verify that there is not a group policy blocking the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Also confirm that UIService.exe is listed as part of the windows startup services.
|Notes||See How to enable RSA ACE/Agent for Windowstracing for debugging purposes to enable agent debug tracing.|
A common location for uiservices.exe is
c:\program files\common files\rsa shared\backend ui
start the service, and see fi teh etst button is working. If it does, this implies system hardening has been done
