Issue exchanging excel file from Excel 64 bits to Excel 32 bits

Hi,

In a xlsm file, I've created a Userform with a WindowsMediaPlayer object.

If I send this file, which has been created on a Excel 32 bits, to a colleague with a Excel 64 bits : no problem, he can open and read the file.

If my colleague "saves as" this file on his PC and send it back to me, I get the following error message just after the warning dialog window about ActiveX :

&H80004005 (-2147467259)

If I remove the WMP object in the Userform and perform the same process, no problem I can read the file when it has been sent back to me.

Any explanation ?

I tried already all the solutions about removing Complements / Add ins etc.

Thank you for your help.
