Check to see if add-in installed

[Sir Babydum GBE]

Hi,

How to I add a line to this code to check whether the add-in is installed and only install it if necessary?

[VBA]Application.DisplayAlerts = False
AddIns("Analysis ToolPak").Installed = True
AddIns("Conditional Sum Wizard").Installed = True
Application.DisplayAlerts = True[/VBA]

If you jsut install them it is fine even if they are already installed. Howevere, if they are not loaded this will fail.

If you just install them it is fine even if they are already installed. However, if they are not loaded this will fail.

Ok, so I guess that's really what I'm asking. At work, if a try to manually install an add-in that isn't loaded, you get a "this is not currently loaded, do you want to load it now?" type of message. Then it downloads the addin from a central server - it seems to know where to look.

So can I programmatically check whether the add-in's are loaded and install them if not?

Perhaps something like this

[vba]
Public Sub Test()
Dim mpaddin As String

On Error GoTo err_handler

Application.DisplayAlerts = False

mpaddin = "Analysis ToolPak"
AddIns(mpaddin).Installed = True

mpaddin = "Conditional Sum Wizard"
AddIns(mpaddin).Installed = True

sub_exit:
Application.DisplayAlerts = True
Exit Sub

err_handler:
MsgBox Err.Number & " - " & Err.Description & vbNewLine & vbNewLine & _
mpaddin
Resume sub_exit
End Sub
[/vba]
