To resolve this, restart the PC and clear cache and cookies in the browser before logging into Access Evo.
Tip: If the problem persists then review the installed Citrix client in Windows - Settings - Add/Remove Programs or Apps, and compare the version with a working user.
Dimensions runs by handshaking the Citrix client installed on the PC with a server Client and these need to be running applicable versions. The client version should automatically update.
Typically the failing user will have an older version, uninstalling Citrix and clearing cache and cookies will prompt a new install of the Citrix client when accessing Dimensions from Access Evo.
