How to check Project 2007 version using VBA?

[ Updated 4/25/2011 – modified code to support Windows 7, please not that this functionality is out of the box in Project Server 2010 and no longer requires such VBA script!]

A great question we heard this morning during the Project 2007 SP2 webcast and every time we release a server and desktop software update for Project 2007 and Project Server 2007, is how do I ensure the desktop contains the proper software updates? For instance how I do ensure that ALL desktop version for Project that connect to Project Server have Service Pack 2 installed?

Thanks to Adrian Jenkins please find below two easy way to achieve this by leveraging VBA (macro) within the Enterprise Global.

A quick demo first:

I try to save a plan and I will get the following warning: and WinProj will automatically be closed! image

In this first approach change MIN_PROJ_VERSION to the latest SP2 version number: 6425 

Feel free to customize the Warning message at will!

    End If

   End If
End Function

Another way to validate the desktop version, uses the file system. The only challenge with this approach is determining the location of the Program Files directory.

 Sub projVersion()
    Dim MainFolderName As String
    Dim LastMod As String
    Dim Created As String
    Dim Size As String
    Dim projVersion As String
      
    Set objShell = CreateObject("Shell.Application")
   
    MainFolderName = "C:\Program Files\Microsoft Office\Office12"
     
    Set FSO = CreateObject("scripting.FileSystemObject")
    Set oFolder = FSO.GetFolder(MainFolderName)
     'error handling to stop the obscure error that occurs at time when retrieving DateLastAccessed
    On Error Resume Next
    For Each fil In oFolder.Files

        Set objFolder = objShell.Namespace(oFolder.Path)
        Set objFolderItem = objFolder.ParseName(fil.Name)
                
        Select Case UCase(fil.Name)
            Case Is = "WINPROJ.EXE"
                LastMod = fil.DateLastModified
                Created = fil.DateCreated
                Size = fil.Size
                MsgBox ("File: " + fil.Name + " Last Modified: " + LastMod + " Created: " + Created + " Size: " + Size)
                'do all of the normal tests here to determine which version you need and which you have. See above.
        End Select
        
    Next

End Sub
