This bug has been fixed in Release 2012a (R2012a). For previous product releases, read below for any possible workarounds:
This error will occur if your installation files are located in a path that contains an invalid character.
For MATLAB versions including R2011b and prior, this error will also occur if your installation files are located in a path that contains a space.
Check all folders containing the MATLAB downloaded installation files and remove any spaces or other invalid (non-alphanumeric) characters.
