Hi Jan, here you have the cleanup script provided by Citrix:  

 

--------------------------------------------------

$iddHwId = "VEN_5853&DEV_1003"
$pnpDispDevPath = "HKLM:\SYSTEM\CurrentControlSet\Enum\SWD\RemoteDisplayEnum"

try
{
    $iddDevEntries = Get-ChildItem -Path $pnpDispDevPath -ErrorAction Stop| Where-Object Name -Match $iddHwId
}
catch
{
    Write-Output "Failed to query remote ID device entries"
    Write-Output $_
    return
}

if ($iddDevEntries.Count -eq 0)
{
     Write-Output "No remote ID device entries found."
     return
}

$iddDevEntries | ForEach-Object {
    
    $devName = ($_.Name -Split "\\")[-1]
    
    try
    {
        Remove-ItemProperty -Path $_.PsPath * -ErrorAction Stop
        Write-Output "Cleared values for $devName"
    }
    catch
    {
        Write-Output "Failed to clear values for $devName"
        Write-Output $_
    }
}

Thanks a lot, this solved my issue after upgrading VDA 2203 CU1 to VDA 2203 CU2. After connecting to the updated VDA user see only a grey screen, the session drops immediately

Problem description:
After updating from LTSR 2203 CU1 to CU2, every user who logs on to the relevant VDA gets a grey screen.
The following event was written in the system event log during the VDA update: ID 1005
The Citrix Universal DLL Injection Driver has encountered an unexpected error.
ID 1003
The Citrix Universal DLL Injection Driver has detected an integrity error during process creation. The Citrix Universal DLL Injection Driver has been disabled.

 

The following registry Key and a reboot of the VDA resolved my problem:

1. Check if the registry HKLM\SYSTEM\CurrentControlSet\Services\CtxUvi = REG_DWORD “UviEnabled” is created. If it's set to "0",  change it to "1".
