Can someone help me in this regard.

I have no idea what the problem is, but it is possible there is an incompatibility with your old (R2010b) version of MATLAB. It would probably be good to upgrade to a more recent MAT:LAB version if you can.

Thanks for your response. I have installed this software in windows 7 with the same matlab version but in windows 10 I am unable to install it.

Perhaps a new version of MATLAB would help - I don’t know. Maybe you “got away” with the old MATLAB version under WINDOWS 7, but not under WINDOWS 10.
