VBA - "FORMAT" function isn't recongnised on 1 computer

Question

I've coded something in VBA to help my co-workers and it's working on 8 computers but on this one computer, everytime I try to start the code, it gives me an error.

Sorry I'm translating from French into English but the error is:

Compilation error: Project or library isn't found

The actual code is:

'           ============================================
'           === TRAITEMENT DES PRODUITS DU GROUPE 10 ===
'           ========== FOURNISSEURS STANDARDS ==========
'           ============================================
            Case 10
            Select Case var_Prix
                Case Is < 25
                    Range(COLLISTE & var_Ligne).Value = Format(99999, "#,####0.0000")
                    Range(COLPRIX2 & var_Ligne).Value = Format(var_Prix / (0.5 - TRANSPORT), "#,####0.0000")
                    Range(COLPRIX3 & var_Ligne).Value = Format(var_Prix / (0.52 - TRANSPORT), "#,####0.0000")
                    Range(COLPRIX4 & var_Ligne).Value = Format(var_Prix / (0.55 - TRANSPORT), "#,####0.0000")
                    Range(COLPRIX5 & var_Ligne).Value = Format(var_Prix / (0.6 - TRANSPORT), "#,####0.0000")
<the code continues>

and it has Format highlighted. Seems like the "Format library" isn't installed but I've tried Google and apparently "Format" is installed with windows or office.

Answer 1

As JKP asked, are there any references marked as "missing"? A missing Ref can cause unpredictable behaviour in other referenced libraries. As a temporary solution, try forcing the reference by putting VBA. before the format, like = VBA.Format(99999, "#,####0.0000") This normally works.

Answer 2

Had this issue recently. Cause was 'something' had disabled the "Analysis Toolpack - VBA" Add-in.

Answer 3

so just had this issue. The solution we found was to add Microsoft Scripting Runtime and Microsoft Word 16.0 Object Library back to the References - VBA Project selection. Not sure which one actually fixed it. But both made the rest of my file work.
