The KB4041681 installs version 4.0.9801.1 of msexcl40.dll.

1. Find prior version (4.0.9801.0) of msexcl40.dll

2. Place in another directory. They suggest the application directory, but since in the next step you will modify registry to point to this older version, it can probably go anywhere.

3. Update registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Jet\4.0\Engines\Excel\win32 to point to the location from step 2.

There is one solution. Replace "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1" with Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\MyExcel.xls; Extended Properties=\"Excel 12.0;HDR = YES; After this change you will have to install 2007 Office System Driver: Data Connectivity Components from link on customer machine.

If you are working with SSIS package then please change your Excel Sheet version 2003 to 2007 in Excel Source or Excel destination.Generally this issue due to excel version.
