Colleagues get error 5 in Excel-file with VBA, but same file works fine on my computer? - vba

Question

We have an Excel-file with a large amount of VBA behind it. The Excel-file works just fine on my computer, but so far 3 of my colleagues (non-IT'ers) have gotten this error:
Runtime error 5:
Invalid procedure call or argument
The error is located on this line, and I don't see why it is throwing an error there because it's just a simple Set (and it works perfectly fine on my computer):
Set MyButton = Application.CommandBars("Attributions").Controls.Add(Type:=msoControlButton, Before:=10)
We all have the exact same Excel-file. I even sent them my version of the file, in which everything is running fine and no errors happen, but even when they open my version of the file they still get the above error on the above line!
What exactly could cause this? We all have Office 2013 and updates are installed automatically. The problem started about 2 weeks ago with one colleague and since this week I heard from two other colleagues that they have the same problem. One even said it suddenly worked again after he moved to a different desk (which I doubt would have an influence) but shortly after, it started getting the error again.
I have absolutely no idea why they get the error, or what might cause it. Seeing as we now all have the same version and they still get the error, I am thinking it might have something to do with Excel itself but that's just my idea.
Does this sound familiar to anyone here? Or does anyone know what might cause this, and how it can be fixed?
Edit: a while ago I checked on my colleagues their computers to see if the CommandBar was present, and it was. Even then the error still happened.

Answer 1

I suggest you to use a function that checks if there is a CommandBar in your Application like this:
Function IsCommandBarValid(cbName As String) As Boolean
Dim i As Long
IsCommandBarValid = True
For i = 1 To Application.CommandBars.Count
If (Application.CommandBars(i).Name = cbName) Then
Exit Function
End If
Next i
IsCommandBarValid = False
End Function
Now, You can use it to see that your user have that CommandBar in his or her Application, then make it like this:
If (Not IsCommandBarValid("Attributions")) Then
Call Application.CommandBars.Add(Name:="Attributions")
End If
' And after this add your code
Set MyButton = Application.CommandBars("Attributions").Controls.Add(Type:=msoControlButton, Before:=10)

Answer 2

Invalid procedure call or argument (Error 5)
Some part of the call can't be completed. This error has the following causes and solutions:
An argument probably exceeds the range of permitted values. For example, the Sin function can only accept values within a certain range. Positive arguments less than 2,147,483,648 are accepted, while 2,147,483,648 generates this error.
Check the ranges permitted for arguments.
This error can also occur if an attempt is made to call a procedure that isn't valid on the current platform. For example, some procedures may only be valid for Microsoft Windows, or for the Macintosh, and so on.
Check platform-specific information about the procedure.
For additional information, select the item in question and press F1 (in Windows) or HELP (on the Macintosh).
