This vb6 code is compatible with VBA:

Function FontIsInstalled(sFont As String) As Boolean
    '' This reference should already be set by default
    '' Tools > References > OLE Automation
    Dim NewFont As StdFont
    On Error Resume Next
    Set NewFont = New StdFont
    With NewFont
        ' Assign the proposed font name
        ' Will not be assigned if font doesn't exist
        .Name = sFont
        ' Return true if font assignment succeded
        FontIsInstalled = (StrComp(sFont, .Name, vbTextCompare) = 0)
        ' return actual font name through arguments
        sFont = .Name
    End With
End Function

using apis there are

EnumFonts The EnumFonts function enumerates the fonts available on a specified device. For each font with the specified typeface name, the EnumFonts function retrieves information about that font and passes it to the application-defined callback function. This callback function can process the font information as desired. Enumeration continues until there are no more fonts or the callback function returns zero.

VB4-32,5,6

Declare Function EnumFonts Lib "gdi32" Alias "EnumFontsA" (ByVal hDC As Long, ByVal lpsz As String, ByVal lpFontEnumProc As Long, ByVal lParam As Long) As Long

The EnumFontFamilies function enumerates the fonts in a specified font family that are available on a specified device. This function supersedes the EnumFonts function.

VB4-32,5,6

Declare Function EnumFontFamilies Lib "gdi32" Alias "EnumFontFamiliesA" (ByVal hdc As Long, ByVal lpszFamily As String, ByVal lpEnumFontFamProc As Long, ByVal lParam As Long) As Long

OK, true to form I found a solution 30 seconds after posting this. This is despite a 10 minute search before resorting to SO....

List installed fonts

The procedure listed below displays a list of installed fonts in Column A of the active worksheet. It uses the FindControl method to locate the Font control on the Formatting toolbar. If this control is not found (i.e. it was removed by the user) a temporary CommandBar is created and the Font control is added to it.

Sub ShowInstalledFonts()
    Set FontList = Application.CommandBars("Formatting").FindControl(ID:=1728)

    'If Font control is missing, create a temp CommandBar
    If FontList Is Nothing Then
        Set TempBar = Application.CommandBars.Add
        Set FontList = TempBar.Controls.Add(ID:=1728)
    End If

    'Put the fonts into column A
    Range("A:A").ClearContents
    For i = 0 To FontList.ListCount - 1
        Cells(i + 1, 1) = FontList.List(i + 1)
    Next i

    'Delete temp CommandBar if it exists
    On Error Resume Next
    TempBar.Delete
End Sub

Is a font installed?

The function below uses the same technique as the ShowInstalledFonts procedure. It returns True if a specified font is installed.

Function FontIsInstalled(sFont) As Boolean
    'Returns True if sFont is installed
    FontIsInstalled = False
    Set FontList = Application.CommandBars("Formatting").FindControl(ID:=1728)

    'If Font control is missing, create a temp CommandBar
    If FontList Is Nothing Then
        Set TempBar = Application.CommandBars.Add
        Set FontList = TempBar.Controls.Add(ID:=1728)
    End If

    For i = 0 To FontList.ListCount - 1
        If FontList.List(i + 1) = sFont Then
            FontIsInstalled = True
            On Error Resume Next
            TempBar.Delete
            Exit Function
        End If
    Next i

    'Delete temp CommandBar if it exists
    On Error Resume Next
    TempBar.Delete
End Function

The statement below demonstrates how to use this function in a VBA procedure. It displays True in a message box if the user's system contains the Comic Sans MS font.
