Word will no longer open through excel VBA - vba

Question

Set up a macro to open word documents through excel. It's been working fine, but after copying the code from the test environment into another file it's refusing to open word on every machine I test it on. Every other part of the macro is working fine, but for some reason word will no longer open via macro.
I've attached the code, but any help would be appreciated. It was working earlier today, and because of this i'm having trouble identifying the problem.
Public Function Method2(ByVal rngl As Range, ByVal strSearch As Variant, ByVal sPath As String)
Dim filePath As String
Dim directory As String
Dim fileName As String
Dim myPath As String
Dim myFile As File
Dim FSO As New FileSystemObject
Dim myFolder As Folder
Dim myExtension As String
Dim mySubFolder As Folder
Dim mySubFolder2 As Folder
Dim objWord
Dim objDoc
Dim rngRange
Dim rng1 As Range
Set myFolder = FSO.GetFolder(sPath)
directory = "S:\File Recipes\"
fileName = "Yaroze_Test"
myExtension = "*.docx*"
Set rng1 = Range("A:A").find(strSearch, , xlValues, xlWhole)
If strSearch = "" Then
MsgBox "Please Enter a Product Code!"
Exit Function
End If
If Not rng1 Is Nothing Then
MsgBox "Product Codes Found!"
For Each mySubFolder In myFolder.SubFolders
For Each mySubFolder2 In mySubFolder.SubFolders
For Each myFile In mySubFolder.Files
If InStr(myFile, strSearch) > 0 Then
fileName = Dir(myPath & myExtension)
MsgBox (myFile.Name)
Do While fileName <> ""
Set objWord = CreateObject("Word.Application")
objWord.Visible = True
ChDrive ("S")
ChDir ("S:\File Recipes\")
filePath = myFile.Path
MsgBox directory
objWord.Documents.Open fileName:=filePath
DoEvents
fileName = Dir
Loop
MsgBox "Task Complete!"
End If
Next
For Each myFile In mySubFolder2.Files
If InStr(myFile, strSearch) > 0 Then
fileName = Dir(myPath & myExtension)
' MsgBox (myFile.Name)
Do While fileName <> ""
Set objWord = CreateObject("Word.Application")
objWord.Visible = True
ChDrive ("S")
ChDir ("S:\File Recipes\")
filePath = myFile.Path
' MsgBox directory
objWord.Documents.Open fileName:=filePath
DoEvents
fileName = Dir
Loop
MsgBox "Task Complete!"
End If
Next
Next
Next
Else
MsgBox "Product Codes Not Found!"
End If
' Set rngRange = _
objWord.Range(objWord.Paragraphs(1).Start, objWord.Paragraphs(1).End - 1)
' rngRange.InsertAfter _
"This is now the last sentence in paragraph one."
I've attempted to test the Macro on other computers to see if it was just the copy of word I was using, and I've tested writing new Macros to open word. They worked initially but other macros are now no longer working. I've tried disabling office from references in VBA and testing with that, and I've made sure it's not an issue with instances of word being left open.
