fm 20dll issue when save as the excel file in 2013 getting unspecified error RRS feed

  • Question

  • We are having application developed in excel 2007 having lot of controls like listbox, check boxes forms etc. we try to run the same application into excel 2013. 
    It works normal if single instance of application is opened but there is a user event where application "SaveAS" itself and perform some calculations and display the result to  user. 
    Once application save itself with new name all the list box controls throws "undefined errors"  and "could not set the column property for list boxes".

    I Googled the issue and find if we replace the excel13 fm20.dll with old fm.dll (excel 2007)  it starts working fine.

    Could you please help me on this?
    Is  Microsoft has provided some fix for this issue if no then when it is expected since it is critical issue for our application as around 1200 users are going to impact
