Problem With Matlab 2013 installation

Hello,

While I;m trying to instal MatLab 2013 on my Win7- 64bit version, I find the following error message:

"The following error was detected while installing aeroblks_fe_common: invalid block type Would you like to retry installing aeroblks_fe_common? If you press No, the installer will exit without completing the installation. More information can be found at C:\Users\ALIBAK~1\AppData\Local\Temp\mathworks_Ali "

and referring to the log, the following event is found:

Would you like to retry installing aeroblks_fe_common? If you press No, the installer will exit without completing the installation. More information can be found at C:\Users\ALIBAK~1\AppData\Local\Temp\mathworks_Ali Bakr.log

Thanks to advice me how to fix this problem.
