Microsoft Sql Server Smo

Im trying to use

Microsoft.SqlServer.Management.Smo

to load a dropdown of available sql server databases.

On my computer it works fine but when i try and run the application on my virtual it throws and unhandled exception that it couldn't load SMO assembly. I know this is because 2005 isn't installed on my virtual but i want to be able to catch this error and just ignore it and load a blank dropdown. I tried putting try catch blocks around the load but it still errors. I then tried instead of importing it i tried to reference smo by using the whole name inside of my try catch block.

 Does anyone know how to catch this errorTry
' Create a new connection to the selected server name

Dim srvConn As New Microsoft.SqlServer.Management.Common.ServerConnection(txtServerName.Text)
Dim srvSql As Microsoft.SqlServer.Management.Smo.Server

' Log in using SQL authentication instead of Windows authentication
srvConn.LoginSecure = False
' Give the login username
srvConn.Login = txtUserID.Text
' Give the login password
srvConn.Password = txtPassword.Text
' Create a new SQL Server object using the connection we created
srvSql = New Microsoft.SqlServer.Management.Smo.Server(srvConn)
' Loop through the databases list
For Each dbServer As Microsoft.SqlServer.Management.Smo.Database In srvSql.Databases
' Add database to combobox
txtDatabase.Items.Add(dbServer.Name)
Next
Catch ex As Exception
MsgBox(ex.Message)
End Try
