Hi, I recently bought a laptop with windows 8 and I installed Matlab R2014a. After updating to windows 8.1 I created a new user account and deleted the old one because I had some problems. But now when I run Matlab I get the following messages in the command window. How can I fix this? Thank you.
C:\Program Files\MATLAB\R2014a\toolbox\local\pathdef.m: Cannot open file: permission denied.

Have you tried running as administrator?

If I run as administrator, it seems to be ok. But I wonder why I have those problems when I run it normally, since it was ok when I used the old account (both accounts are administrators). Also, I can't find the startup.m file anywhere.

Different versions of Windows seem to have had different requirements with respect to needing administrator privileges to run certain programs. I'm not really familiar with what these are, but I seem to remember some version where I had to always run Matlab as an administrator in order to save my path variable.
startup.m does not exist unless you create it yourself.
