When installing the MATLAB Component Runtime (MCR) using MCRinstaller.exe, the installation aborts and you receive the following error message:

"The wizard was interrupted before MATLAB component Runtime 7.5 could be completely installed.\par You system has not been modified. To complete installation at another time, please run setup again."

Depending on which version of the Microsoft installer you have on your system, you might see this error message instead:
"Error 1304 writing to file MWArray.dll Verify that you have access to that directory and later an Internal Error 2350 popup.


  1. Download the Microsoft Visual C++ Redistributable Package. For 32-bit systems, download vcredist_x86.exe (available here). For 64-bit systems, download vcredist_x64.exe (available here). These self-extracting executable files install runtime components of Visual C++ Libraries required to run applications developed with Visual C++ on a computer that does not have Visual C++ 2005 installed
  2. Install the package on the target computer by double-clicking on the file you downloaded.
  3. Re-execute MCRInstaller.exe, but see note below.

NOTE: When you run the MCR installer, you will see a pop-up message indicating that .Net Framework is not installed. Click the option to continue without installing .NET Framework.
