1  Important notes on Dymola 
Installation on Windows 
To translate models on Windows, you must also install a supported compiler. The compiler 
is not distributed with Dymola.  
Note that administrator privileges are required for installation. 
Two types of compilers are supported on Windows in Dymola 2015: 
Microsoft Visual Studio C++ 
This is the recommended compiler for professional users. 
Note  that  free  Microsoft compiler  versions earlier than Microsoft Visual Studio Express 
2008 are not supported (concerning  full versions, some earlier versions are supported). 
Refer to section “Compilers” on page 41 for more information. 
GCC 
Dymola 2015 introduces limited support for the MinGW GCC compiler. For the list of 
current limitations; refer to section “GCC compiler supported” on page 21. 
Installation on Linux 
To translate models, Linux relies on a GCC compiler, which is usually part of the Linux 
distribution. Refer to section “Dymola versions on Linux and operating system versions, and 
compiler” on page 42 for more information.
