Question

I am receiving:

Run-time error ‘1004’: Cannot run macro Makros.xlm!MakroIni. The
macro may not be available in this workbook or all macros may be
disabled.

…when running a Macro in certain instances of Excel 2010. In some Excel 2010 installations and Excel 2003 it works fine.

There are 2 Workbooks involved: Macro.xlm and Username.xls. Both files are stored on a remote server.

The Macro crashes when executing:

Workbooks.Open Makro_Path & Makro_Nam, ReadOnly:=True
Application.Run Makro_Nam & "!MakroIni", WbTyp

The first line is proper executed and all macros are visible.
Makro_Nam is defined as:

Public Const Makro_Nam As String = "Makros.xlm"

What can i do?

Answer 1

Actually the cause was Excel 64 bit.

The Makro.xlm worksheet contained this function definitions:

Private Declare  Function FindFirstFile Lib "kernel32.dll" Alias "FindFirstFileA" ( _
ByVal lpFileName As String, _
ByRef lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare  Function FindNextFile Lib "kernel32.dll" Alias "FindNextFileA" ( _
ByVal hFindFile As Long, _
ByRef lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare  Function FindClose Lib "kernel32.dll" ( _
ByVal hFindFile As Long) As Long
Private Declare  Function FileTimeToLocalFileTime Lib "kernel32.dll" ( _
ByRef lpFileTime As FILETIME, _
ByRef lpLocalFileTime As FILETIME) As Long
Private Declare  Function FileTimeToSystemTime Lib "kernel32.dll" ( _
ByRef lpFileTime As FILETIME, _
ByRef lpSystemTime As SYSTEMTIME) As Long

I changed them to ptrsafe:

Private Declare PtrSafe Function FindFirstFile Lib "kernel32.dll" Alias "FindFirstFileA" ( _
ByVal lpFileName As String, _
ByRef lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare PtrSafe Function FindNextFile Lib "kernel32.dll" Alias "FindNextFileA" ( _
ByVal hFindFile As Long, _
ByRef lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare PtrSafe Function FindClose Lib "kernel32.dll" ( _
ByVal hFindFile As Long) As Long
Private Declare PtrSafe Function FileTimeToLocalFileTime Lib "kernel32.dll" ( _
ByRef lpFileTime As FILETIME, _
ByRef lpLocalFileTime As FILETIME) As Long
Private Declare PtrSafe Function FileTimeToSystemTime Lib "kernel32.dll" ( _
ByRef lpFileTime As FILETIME, _
ByRef lpSystemTime As SYSTEMTIME) As Long

Now it seems to work.
