Error using xlsread (line 251) in windows 10

Hi all, I have been using without any problem Matlab R2015b on windows 8 up to yesterday when I had to update to Windows 10. Now I get the following error when using xlsread:

Error using xlsread (line 251).

Paradoxically using the option 'basic' it works, but I do not want to go through tons of code I already programmed to use this fallback solution.

Do you have any idea of why this could happen?

Thanks a lot for your help.

What is the complete error message that you get?

The basic option really just changes the way MATLAB reads the data. By default it uses Microsoft COM objects. For this reason I would suspect it has to do with your Microsoft products themselves, but there is no real way to tell. I would try and contact support (MathWorks support) as they may have some intuition into this problem.

The complete error is simply:

Error using xlsread (line 251)

Using basic changes everything, dates for example are not read anymore as dates but as integers. For me it would be a disaster to re-write all the code based on this.

open your excel and click off all COM add-ins,then try xlsread again
