"Run-time error 462 : The remote server machine does not exist or is unavailable" when running VBA code a second time

Question

The code below is working fine the first time I run it, but when I need to run it a second time, it gives me this error:

Run Time error '462': the remote server machine does not exist or is unavailable

It doesn't happen all the time so I suppose it has something to do with Word (not) running in the background...? What am I missing here?

Sub Docs()

Sheets("examplesheet").Select

Dim WordApp1 As Object
Dim WordDoc1 As Object

Set WordApp1 = CreateObject("Word.Application")
WordApp1.Visible = True
WordApp1.Activate

Set WordDoc1 = WordApp1.Documents.Add

Range("A1:C33").Copy

WordApp1.Selection.PasteSpecial Link:=False, DataType:=wdPasteRTF, _
Placement:=wdInLine, DisplayAsIcon:=False

Application.Wait (Now + TimeValue("0:00:02"))

WordDoc1.PageSetup.TopMargin = CentimetersToPoints(1.4)
WordDoc1.PageSetup.LeftMargin = CentimetersToPoints(1.5)
WordDoc1.PageSetup.BottomMargin = CentimetersToPoints(1.5)

' Control if folder exists, if not create folder
If Len(Dir("F:\documents\" & Year(Date), vbDirectory)) = 0 Then
MkDir "F:\documents\" & Year(Date)
End If

WordDoc1.SaveAs "F:\documents\" & Year(Date) & "\examplename " & Format(Now, "YYYYMMDD") & ".docx"

WordDoc1.Close

Answer 1

First problem : Run-time error '462' : The remote server machine does not exist or is unavailable.

The issue here is the use of :

1. Late Biding : Dim Smthg As Object or
2. Implicit references : Dim Smthg As Range instead of
   Dim Smthg As Excel.Range or Dim Smthg As Word.Range

So you need to fully qualified all the variables that you set (I've done that in your code)

Second problem

You work with multiple instances of Word and you only need one to handle multiple documents.

So instead of creating a new one each time with :

Set WordApp = CreateObject("Word.Application")

You can get an open instance (if there is one) or create one with that code :

On Error Resume Next
Set WordApp = GetObject(, "Word.Application")
If Err.Number > 0 Then Set WordApp = CreateObject("Word.Application")
On Error GoTo 0

And once you've put this at the start of your proc, you can use this instance until the end of the proc and before the end, quit it to avoid having multiple instances running.

Here is your code reviewed and cleaned, take a look :

Sub Docs()

Dim WordApp As Word.Application
Dim WordDoc As Word.Document

' Control if folder exists, if not create folder
If Len(Dir("F:\documents\" & Year(Date), vbDirectory)) = 0 Then MkDir "F:\documents\" & Year(Date)

' Get or Create a Word Instance
On Error Resume Next
Set WordApp = GetObject(, "Word.Application")
If Err.Number > 0 Then Set WordApp = CreateObject("Word.Application")
On Error GoTo 0

Workbooks("exampleworkbook.xlsm").Sheets("examplesheet").Range("A1:C33").Copy

    .Visible = True
    .Activate
    Set WordDoc = .Documents.Add
    .Selection.PasteSpecial Link:=False, DataType:=wdPasteRTF, _

If this is running in Excel then you probably need to specify that CentimetersToPoints is coming from the Word library. As it stands, VBA has to guess and sometimes it probably can't find it. So try:

wdApp.CentimetersToPoints
