I need help in
Too
I have had issues with addins that are installed (and in the VBE) not being available via user's Addin on Exel 2013 (in a work environment).
Tinkering with the solution from Chris C gave a good workaround.
Dim a As AddIn
Dim wb As Workbook
On Error Resume Next
With Application
.DisplayAlerts = False
For Each a In .AddIns2
Debug.Print a.Name, a.Installed
If LCase(Right$(a.Name, 4)) = ".xla" Or LCase(Right$(a.Name, 5)) Like ".xla*" Then
Set wb = Nothing
Set wb = .Workbooks(a.Name)
wb.Close False
Set wb = .Workbooks.Open(a.FullName)
End If
Next
.DisplayAlerts = True
End With
