Hello everyone,
I have recently unistalled matlab r2015 on my Windows7 (32bit) machine and now I tried to re-install the same version with a campus license on the same computer, but it doesn't work. The installer application encountered an unexpected error and it stoped with the specific error message in log file as follow:
Task MATLAB R2015b Startup Accelerator for C:\Program Files\MATLAB\R2015b does not exist
java.lang.NullPointerException

I've tried to install another version, it seems work, but I still wonder what's the problem with r2015 reinstallation? I' ll appreciate it if anyone could help.

I understand that you are facing an installation issue. Such errors generally occur due to corrupt files being used while performing Installation or uninstallation.
May you try performing a clean installation of MATLAB R2015b on your system using the link below?
