Option 1 (Agent Upgrade with Cache Rebuild)

1. Download and install the latest version of the WEM agent

Option 2 (Manual steps to rebuild agent cache)

1. In Task Manager, terminate the agent process (VUEMUIAgent.exe)
2. Stop "Citrix WEM Agent Host Service" and "Netlogon" services
3. Navigate to "C:\Program Files (x86)\Citrix\Workspace Environment Management Agent\Local Databases" and delete the two .db files located there
4. Start the "Citrix WEM Agent Host Service" and "Netlogon" service
5. Relaunch the agent

Option 3 (Script to rebuild agent cache)

Run the following script on the agent to force the cache to rebuild instead of refreshing:

#This script is used to troubleshoot WEM Agent refresh issues

$LocalDatabaseDir = 'C:\Program Files (x86)\Citrix\Workspace Environment Management Agent\Local Databases'
$LocalDatabases =Get-ChildItem "C:\Program Files (x86)\Citrix\Workspace Environment Management Agent\Local Databases\*.db"

#This section is used to kill the VUEMUIAgent.exe process if it is running
$ProcessName = Get-Process -Name VUEMUIAgent -ErrorAction SilentlyContinue
$Services = "Netlogon","Citrix WEM Agent Host Service"
if ($ProcessName)
  {
   Stop-Process -Name $([string]$ProcessName.ProcessName)
   Write-Host "VUEMUIAgent has stopped"
  }
else
   {
    Write-Host "VUEMUIAgent is not running"
   }

#Stop Norskale and Netlogon services
foreach ($service in $Services)
   {
       Stop-Service -Name $service -Force
       Write-Host "$service has stopped."
   }
PAUSE

#Delete the WEM Agent Cache
cd $LocalDatabaseDir
Remove-Item $LocalDatabases
Write-Host "Files have been deleted"
PAUSE

#Start Netlogon Service which will start Norskale
$WEMAgent = 'C:\Program Files (x86)\Citrix\Workspace Environment Management Agent\VUEMUIAgent.exe'
foreach ($service in $Services)
   {
       Start-Service $service
       Write-Host "$service is running."
   }
PAUSE
Start-Process "C:\Program Files (x86)\Citrix\Workspace Environment Management Agent\AgentCacheUtility.exe" -refreshcache
Start-Process -FilePath $WEMAgent

Problem Cause

The latest update of WEM service provides an update to the database schema.  The current agent cache is not aware of the change and a rebuild of the cache is required.

WEM agent does not launch automatically on logon
