vba – MS Access 2010, Excel 2010, Windows Server 2008 R2 64-bit: SaveAs method of Workbook class failed

Posted by: admin April 23, 2020 Leave a comment


Services used: MS Access 2010, Excel 2010, Windows Server 2008 R2 (64-bit)

In our MS Access database, we wrote a process that exports queries to .xlsx format and saves them on the network drive. It uses this syntax:

objxl.ActiveWorkbook.SaveAs filename, FileFormat:=xlOpenXMLWorkbook


xlWBk.SaveAs filename, FileFormat:=xlOpenXMLWorkbook

where objxl is declared as:

Private objxl As Object

And files are opened via:

Dim xlWBk As Object

If objxl Is Nothing Then
    Set objxl = CreateObject("Excel.Application")
End If

If Dir(sourceFile) = vbNullString Then
    Set xlWBk = objxl.Workbooks.Add
    Set xlWBk = objxl.Workbooks.Open(sourceFile)
    blnFileExists = True
End If

This code works fine when we run it manually. I am reasonably confident that the code is correct, but I’m posting it here just in case.

However, we need to automate this database so we have it run from an account via scheduled task, set to run even if the account is not logged in (and this account has admin rights, etc). Unfortunately, when running the program like this, we get this error in our logs:

"SaveAs method of Workbook class failed."

We’ve verified that it isn’t a network read/write problem (it writes all sorts of other files, such as .txt and .pdf, just fine to the network drive. This issue appears to be localized to Excel).

We’ve tried a fix as per this post: https://stackoverflow.com/a/1090864/5239568

But nothing seems to be working so far.

How to&Answers:

Finally got it fixed. Here was what worked, in case anyone in the future has this same error.

We added BOTH folders:



My first suggestion would be to check for Excel add-ins that run automatically – especially a corporate security document classification / copyright notice script.

Your next suspect is Trusted Locations, which I’ve mentioned elsewhere under the heading Trusted Locations: a source of misleading error messages.

This is the leading suspect, because ‘Trusted Locations’ is a security setting that interdicts scripts and automated COM objects, but not manual actions. Or at least, not all ‘user is present’ manual actions. So you won’t catch it by trying to reproduce the error manually – and you might find that your attempts at debugging give inconsistent results.

You can set a folder to be a trusted location manually, in any Microsoft Office Application, under the ‘File’ menus as Options; Trust Center; Trusted Locations – but this is user-specific and you might not be able to do it for whoever (or whatever) runs your application. So this should give you a hint about automating it:

VBA Code to set a Trusted Location:

Public Sub TrustThisFolder(Optional FolderPath As String, _
                           Optional TrustSubfolders As Boolean = True, _
                           Optional TrustNetworkFolders As Boolean = False, _
                           Optional sDescription As String)

‘ Add a folder to the ‘Trusted Locations’ list so that your project’s VBA can
‘ open Excel files without raising errors like “Office has detected a problem
‘ with this file. To help protect your computer this file cannot be opened.”

‘ Ths function has been implemented to fail silently on error: if you suspect
‘ that users don’t have permission to assign ‘Trusted Location’ status in all
‘ locations, reformulate this as a function returning True or False

‘  This should be used with caution: although I regard Microsoft’s rationale
‘  for ‘Trusted Locations’ to be flawed (in this specific case, perverse and
‘  worse than ineffective) bypassing a security feature is never a good idea
‘  without letting the users know what they are doing, and offering a choice

‘  You are strongly advised to keep the confirmation dialogue, unless you’ve
‘  run into something stupid – like refusing to open files in the user’s own
‘  local temp folder – which is what we’re dealing with here, in basExcelSQL

Note that this code is dependent on user intervention to confirm removing the ‘Trusted Location’ setting. You can remove the dialogues, but I’d urge you to consult your sysadmin before you do.

(Note: I’m using ‘popup’ dialogue boxes, which disappear automatically after a preset interval, allowing the code to continue. Ask if you want the code)

After that, it gets arcane. Here’s the code I wrote for the last time I had to use a separate instance of Excel.exe to open a file:

With New Excel.Application

    .ShowStartupDialog = False
    .Visible = False
    .EnableCancelKey = xlDisabled
    .UserControl = False
    .Interactive = False
    .EnableEvents = False

    .DisplayAlerts = False
    .AutomationSecurity = msoAutomationSecurityForceDisable

    .Workbooks.Add ‘ Calculation property is not available if no workbooks are open
    If .Calculation <> xlCalculationManual Then
        .Calculation = xlCalculationManual
    End If

    On Error Resume Next

    For i = .Workbooks.Count To 1 Step -1
        .Workbooks(i).Close False
    Next i

    On Error Resume Next

    For i = 1 To .AddIns.Count
        If .AddIns(i).IsOpen Then
            .AddIns(i).Installed = False
        End If
    Next i

    For i = 1 To .COMAddIns.Count
        If .COMAddIns(1).progID Like “*Information*Classification*” Then
            ‘ no action
            .COMAddIns(i).Connect = False
            If Not .COMAddIns(i).Object Is Nothing Then
            End If
        End If
    Next i

End With

You’ll note the  ‘On error Resume Next’  in there: some Add-Ins can’t be closed.

After that, it’s phases of the moon and human sacrifice. Or, maybe, a quick look at the other answers on Stack Oveflow.
