Workflow Manager - Add-WFHost fails with "Could not load file" error

Question

Hello! I'm not sure that its Sharepoint related topic but..
I'm trying to install Workflow Manager using Powershell. I'm successfully created ServiceBus farm, create namespace, Add-SBhost etc. Also, i created WF Farm using New-WFFarm.
Now i'm got SB Configuration and try to add my first host to WF Farm using standard cmdlets:
$SBClientConfiguration = Get-SBClientConfiguration -Namespaces 'WorkflowDefaultNamespace'
(it successfuly gives me some endpoint definitions)
Add-WFHost -WFFarmDBConnectionString $WFFarmDBConStr -RunAsPassword $ServiceAccountPassword -EnableFirewallRules $true -SBClientConfiguration $SBClientConfiguration -CertificateAutoGenerationKey $CertificateAutoGenerationKey
where
$WFFarmDBConStr is typical connection string, i also used this to Get-WFFarm with no errors.
$ServiceAccountPassword and $CertificateAutoGenerationKey are secure strings.
But trouble appears with SBClientConfiguration, cmdlet returns error:
"Cannot validate argument on parameter 'SBClientConiguration'. Could not load file or assebly 'Microsoft.ServiceBus, Version=1.8.0.0, Culture=neutral, PublicKeyToken=<SomeTokenSymbolsHere> or one of its dependencies. The system cannot
find the file specified."
What file it tries to load? I've installed all WorkflowManager binaries with
webpicmd /Install /Product:WorkflowManagerRefresh key and don't know, what can be cause.

Hi lehus,
According to your description, my understanding is that you got an error when you configured Workflow Manager using PowerShell.
Please try to use the following PowerShell command, compare the result:
Add-WFHost -WFFarmDBConnectionString $WFFarmDBConStr -RunAsPassword $ServiceAccountPassword -EnableFirewallRules $true -SBClientConfiguration $SBClientConfiguration
–EnableHttpPort -CertificateAutoGenerationKey $CertificateAutoGenerationKey
-Verbose
Check your process as:

In addition, whether you could install and configure Workflow Manager with Workflow Manager Configuration Wizard. Please have a try as:
