Installing Matlab R2015b in Win 10 I received: Error finding installer class. An exception occurred while looking for class. What to do? The same setup.exe in Windows 7 works well.

These are the typical problems that cause the error message you described:
- Non-ASCII characters (e.g. !@#$&^?) are present in the path to the MATLAB installation folder, or the name of the folder itself
- Non-ASCII characters are present in the path to the Windows TEMP folder, the name of the TEMP folder itself, or the values of the TEMP and/or TMP environment variables
- Non-ASCII characters are present in the path to the folder containing the MATLAB installer, or the name of the folder itself
- There is a problem with the installation files (damaged DVD, corrupt or incomplete downloads)
Make sure none of these issues is causing the error and, if the error persists, I'd call MathWorks Technical Support. They have a team dedicated to installation issues.
