I don't think the version will make any difference. I don't believe that search and replace with wildcards works in any version of PowerPoint.
In Word for example you can use a regx expression but not in PPT unless you do it in code.
Do you know (or can research) how to use basic vba code?
If so this MIGHT work but be sure to use a copy of your work.
Sub use_regex()
Dim regX As Object
Dim osld As Slide
Dim oshp As Shape
Dim strInput As String
Dim b_found As Boolean
Set regX = CreateObject("vbscript.regexp")
With regX
.Global = True
.Pattern = "\(\s?\d+ of \d+\s?\)"
End With
For Each osld In ActivePresentation.Slides
For Each oshp In osld.Shapes
If oshp.HasTextFrame Then
If oshp.TextFrame.HasText Then
strInput = oshp.TextFrame.TextRange.Text
b_found = regX.Test(strInput)
If b_found = True Then
strInput = regX.Replace(strInput, "")
oshp.TextFrame.TextRange = strInput
End If
End If
End If
Next oshp
Next osld
Set regX = Nothing
End Sub
