Detecting Project Client Version

We have heard from a lot of customers that they want to block the Project Client from connecting to the server if it does not have the latest updates to install. To solve this, you can add one of the two VBA scripts to the enterprise global to check the client version. Both solutions are not perfect, but they may help solve the problem.

The first solution looks at the file version. The only slight issue with this solution 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

The second solution looks at a registry key for the Project Client version and it was written with the help of https://www.arcatapet.net/vbregget.cfm:

 Const MIN_PROJ_VERSION = 6330

Const HKEY_CLASSES_ROOT = &H80000000
Const HKEY_CURRENT_USER = &H80000001
Const HKEY_LOCAL_MACHINE = &H80000002
Const HKEY_USERS = &H80000003

Const ERROR_SUCCESS = 0&
Const REG_SZ = 1&                          ' Unicode nul terminated string
Const REG_DWORD = 4&                       ' 32-bit number

Const KEY_QUERY_VALUE = &H1&
Const KEY_SET_VALUE = &H2&
Const KEY_CREATE_SUB_KEY = &H4&
Const KEY_ENUMERATE_SUB_KEYS = &H8&
Const KEY_NOTIFY = &H10&
Const KEY_CREATE_LINK = &H20&
Const READ_CONTROL = &H20000
Const WRITE_DAC = &H40000
Const WRITE_OWNER = &H80000
Const SYNCHRONIZE = &H100000
Const STANDARD_RIGHTS_REQUIRED = &HF0000 Const STANDARD_RIGHTS_READ = READ_CONTROL Const STANDARD_RIGHTS_WRITE = READ_CONTROL Const STANDARD_RIGHTS_EXECUTE = READ_CONTROL Const KEY_READ = STANDARD_RIGHTS_READ Or KEY_QUERY_VALUE Or KEY_ENUMERATE_SUB_KEYS Or KEY_NOTIFY Const KEY_WRITE = STANDARD_RIGHTS_WRITE Or KEY_SET_VALUE Or KEY_CREATE_SUB_KEY Const KEY_EXECUTE = KEY_READ

Sub ProjectVer()

    Dim projVersion As String
    Dim version As String
    
    projVersion = RegGetValue$(HKEY_LOCAL_MACHINE, "Software\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\00002109B30000000000000000F01FEC\InstallProperties", "DisplayVersion")
    version = Mid(projVersion, 6, 4)
    If (CInt(version) < MIN_PROJ_VERSION) Then
        
        MsgBox "Your version of Winproj.exe is not valid and may cause problems." & Chr(13) & Chr(13) & _
        "The installation of new version of Microsoft Project is required!" & Chr(13) & Chr(13) & _
        "Required Version: " & Left(projVersion, 5) & MIN_PROJ_VERSION & ".XXXX" & (Chr(13)) & _
        "Found Version:     " & projVersion & Chr(13) & Chr(13) & _
        "Microsoft Project will now Exit." _
        , vbExclamation, "Program Version Check"
        
        Application.FileExit pjDoNotSave
        
    End If
    
End Sub

Function RegGetValue$(MainKey&, SubKey$, value$)
   ' MainKey must be one of the Publicly declared HKEY constants.
   Dim sKeyType&       'to return the key type.  This function expects REG_SZ or REG_DWORD
   Dim ret&            'returned by registry functions, should be 0&
   Dim lpHKey&         'return handle to opened key
   Dim lpcbData&       'length of data in returned string
   Dim ReturnedString$ 'returned string value
   Dim ReturnedLong&   'returned long value
   If MainKey >= &H80000000 And MainKey <= &H80000006 Then
      ' Open key
      ret = RegOpenKeyExA(MainKey, SubKey, 0&, KEY_READ, lpHKey)
      If ret <> ERROR_SUCCESS Then
         RegGetValue = ""
         Exit Function     'No key open, so leave
      End If
      
      ' Set up buffer for data to be returned in.
      ' Adjust next value for larger buffers.
      lpcbData = 255
      ReturnedString = Space$(lpcbData)

      ' Read key
      ret& = RegQueryValueExA(lpHKey, value, ByVal 0&, sKeyType, ReturnedString, lpcbData)
      If ret <> ERROR_SUCCESS Then
         RegGetValue = ""   'Value probably doesn't exist
      Else
        If sKeyType = REG_DWORD Then
            ret = RegQueryValueEx(lpHKey, value, ByVal 0&, sKeyType, ReturnedLong, 4)
            If ret = ERROR_SUCCESS Then RegGetValue = CStr(ReturnedLong)
        Else
            RegGetValue = Left$(ReturnedString, lpcbData - 1)
        End If
    End If
      ' Always close opened keys.
      ret = RegCloseKey(lpHKey)
   End If
End Function

  I'm interested in implementing this but I don't know how to add the code to the Enterprise Global. I have some experience with writing VBScript against COM objects. If you can point me in the right direction I should be able to figure things out. Thank you!!
